CVE-2026-75525 1 Open-reception 1 Appointment-booking-software 2026-10-23 5.3 Medium
OpenReception's appointment booking software provides an end-to-end encrypted appointment booking platform. In versions 2.1.0 and prior, an unauthenticated attacker can store an arbitrary ML-KEM-768 public key under any existing user's identity in any tenant's staff-crypto recipient directory. The product's design guarantees that appointment data is end-to-end encrypted to staff members and that the staff recipient directory is not attacker-writable, so that even administrators and the operator cannot read patient data. This endpoint breaks that guarantee for an unauthenticated remote actor: it allows writing an arbitrary encryption recipient into the recipient directory of any tenant. The injected key receives the tunnel key of every appointment booked afterward in that tenant, because booking clients encrypt to all active staff keys. The attacker holds the corresponding secret key and is a persistent, unauthorized recipient of that key material. At time of publication, there are no publicly available patches.
CVE-2026-19947 1 Zephyrproject 1 Zephyr 2026-10-23 5.3 Medium
The device multiplexer pseudo-driver in drivers/misc/devmux/devmux.c exposes two system calls, devmux_select_get() and devmux_select_set(). When CONFIG_USERSPACE is enabled, their user-mode verifiers z_vrfy_devmux_select_get() and z_vrfy_devmux_select_set() forwarded directly to the kernel implementations without performing any kernel-object validation — no k_object_access_check() and no driver object check. Compounding this, DEVICE_DT_INST_DEFINE() registered devmux instances with a NULL driver API pointer, which causes scripts/build/gen_kobject_list.py to skip them entirely, so a devmux device had no struct k_object and no permission on it could be granted or withheld in the first place. Any thread running in user mode can reach the defect: device pointers such as DEVICE_DT_GET(DT_NODELABEL(devmux0)) are compile-time constants available to application code, and the syscall accepted them from a thread that had never been granted access to the device. The kernel implementations do validate the pointer against the static devmux instance table and bounds-check the selection index, so this is not a memory-safety issue; the failure is purely one of authorization. Exposure requires CONFIG_USERSPACE=y together with the experimental CONFIG_DEVMUX=y (which depends on CONFIG_DEVICE_MUTABLE) and a zephyr,devmux devicetree node. An unprivileged user-mode thread can read and change which downstream device a multiplexer forwards to, bypassing the userspace object-permission model. Because a devmux forwards the data, configuration and API of the selected device — its documented use being zephyr,console and zephyr,shell-uart switching — an attacker can suppress console, log and shell output, redirect that output to a downstream device it is able to observe, or flip the selection underneath another thread that is legitimately using the multiplexer. The impact is bounded to the devicetree-fixed set of downstream devices; no out-of-bounds access or arbitrary pointer dereference is reachable. The fix declares __subsystem struct devmux_driver_api and attaches a DEVICE_API(devmux, devmux_api) instance to each devmux device so that it becomes a tracked K_OBJ_DRIVER_DEVMUX kernel object, and adds K_OOPS(devmux_inst_get(dev) == SIZE_MAX) plus K_OOPS(k_object_access_check(dev) != 0) to both verifiers.
CVE-2026-105942 1 Apache 1 Pulsar 2026-10-23 N/A
When a configured proxy role sends a request to the broker on behalf of another user (the original principal), the broker is designed to authorize both the proxy role and the original principal and to allow the request only if both are authorized, so that the original principal cannot exceed its own permissions. Two flaws weakened this check. First, the original principal was authorized with the proxy's authentication data instead of its own. On the admin REST API of the broker and the functions worker, this applied to every proxied request. On the Pulsar binary protocol, it applied when the proxy did not forward the client's credentials to the broker, which was the default of the Pulsar proxy in the affected versions. Authorization providers that resolve permissions from the role name only, such as the default authorization provider, are not affected by this flaw. The multi-role token authorization provider (MultiRolesTokenAuthorizationProvider), added in Apache Pulsar 2.8.1, resolves roles from the role claim of the token in the authentication data it is given. When a proxy authenticates to the broker with its own token, the original principal was therefore authorized with all roles in the proxy's token. If any of those roles is a superuser or tenant admin role, any user whose requests are forwarded by that proxy can perform operations that need those permissions without holding them. Custom authorization providers that use the authentication data could be affected in a similar way. Second, independently of the authorization provider, the tenant admin check of a proxied admin REST API request succeeded without checking the original principal when the proxy role was itself an admin role of the tenant. In deployments where a proxy role is a tenant admin, including with the default authorization provider, any user whose requests are forwarded by that proxy could perform tenant administration operations on that tenant. This behavior is present from 2.8.4 in the 2.8.x releases, from 2.9.3 in the 2.9.x releases, and from 2.10.1 onwards. Deployments that use neither the multi-role token authorization provider nor a custom provider that uses the authentication data are not affected by the first flaw, and with the multi-role token authorization provider, neither are deployments whose proxies do not authenticate to the broker with a token. Deployments in which no proxy role is listed as an admin role of a tenant are not affected by the second flaw. A proxy role that is a superuser but is not listed as a tenant admin does not trigger it, because the tenant admin check of the built-in authorization providers only considers the tenant's admin roles; this can differ for custom authorization providers that treat superusers as tenant admins. In fixed versions, both the proxy role and the original principal are authorized for each proxied request, and the original principal is authorized only with its own authentication data. With the multi-role token authorization provider, the roles of a forwarded token are used for the original principal only when that token authenticates as the original principal; otherwise only the original principal's role name is used. For tenant admin checks, the proxy role and the original principal must each be a superuser or a tenant admin of the tenant. This issue affects Apache Pulsar versions from 2.8.1 before 4.0.14 and from 4.1.0 before 4.2.5. - 4.0.x version users should upgrade to at least 4.0.14. - 4.1.x and 4.2.x version users should upgrade to at least 4.2.5. Users operating versions prior to those listed above should upgrade to the aforementioned patched versions or newer versions. The currently supported Apache Pulsar release lines are 4.0.x and 5.0.x. The supported versions schedule is available at https://pulsar.apache.org/contribute/release-policy/.
CVE-2026-105938 1 Apache 1 Pulsar 2026-10-23 N/A
Apache Pulsar namespaces can restrict which roles may use a subscription, either with the Prefix subscription authentication mode, which requires a subscription name to start with the role name, or by granting permission on a subscription to specific roles. Topic-level subscription operations, such as consuming, skipping messages, resetting a cursor or deleting a subscription, apply these subscription policies. Several admin REST API operations that act on subscriptions did not apply them: - the namespace-level and bundle-level clear backlog operations, both for a named subscription and for all subscriptions; - the namespace-level and bundle-level unsubscribe operations; - the topic-level operation that expires messages for all subscriptions of a topic. With the default authorization provider, the namespace-level operations require only consume permission granted on the namespace, and the expire-all operation requires only consume permission on the topic. As a result, when authentication and authorization are enabled and a namespace uses the Prefix subscription authentication mode or subscription permissions, an authenticated user with such consume permission can clear the backlog of, expire messages of, or delete a subscription that the policies would deny to that user. Tenant admin or superuser access is not required. The clear backlog operations can also be applied to the cursors used for geo-replication, so that messages not yet replicated to a remote cluster are skipped. Deployments that do not configure the Prefix subscription authentication mode or subscription permissions (the defaults) are not affected by this bypass, because consume permission on the namespace or topic already allows these operations there. This impact analysis assumes that Pulsar has been configured with the default authorization provider. For custom authorization providers, the impact could be different. The impact is on the integrity of subscription state. Clearing or expiring the backlog moves the subscription's cursor forward, so unacknowledged messages are no longer delivered to the subscription's consumers. The unsubscribe operation deletes a subscription that has no connected consumers. Skipped messages can be permanently deleted once no other subscription or the namespace's retention policy keeps them. The issue does not allow reading message contents, changing permissions or policies, or accessing other namespaces, and it does not affect the availability of the broker. In fixed versions, the namespace-level and bundle-level operations for a named subscription apply the subscription policies to that subscription, and the operations for all subscriptions, when requested by a user who is not a tenant admin or superuser, only act on the subscriptions that the user may access. Clearing the backlog of geo-replication cursors requires tenant admin or superuser access. Topic-level subscription operations apply the subscription policies for all types of authentication data, including that of the anonymous user role. This issue affects Apache Pulsar versions from 2.8.0 before 4.0.14 and from 4.1.0 before 4.2.5. - 4.0.x version users should upgrade to at least 4.0.14. - 4.1.x and 4.2.x version users should upgrade to at least 4.2.5. All brokers in a cluster must be upgraded before relying on the namespace-level restrictions, because brokers that have not been upgraded do not apply them when they receive the internal per-bundle requests. Users operating versions prior to those listed above should upgrade to the aforementioned patched versions or newer versions. The currently supported Apache Pulsar release lines are 4.0.x and 5.0.x. The supported versions schedule is available at https://pulsar.apache.org/contribute/release-policy/. Users who cannot upgrade immediately can reduce exposure by restricting network access to the broker's admin REST API to trusted administrative clients.
CVE-2026-105937 1 Apache 1 Pulsar 2026-10-23 N/A
Apache Pulsar shadow topics (PIP-180) are topics that read the stored messages of a source topic from that topic's managed ledger. The source topic is selected by setting the reserved topic property PULSAR.SHADOW_SOURCE. The admin REST API accepts this property when creating a non-partitioned or partitioned topic and when updating the properties of an existing topic. On these paths the broker authorizes the caller only against the topic being created or updated. It does not authorize the caller against the source topic named in the property. The existing authorization for shadow topic configuration (the SHADOW_TOPIC topic policy on the source topic) is applied only to the source-side shadow topics admin API, not to these paths. As a result, an authenticated user who is allowed to create topics or update topic properties in one tenant can bind a topic in that tenant to a persistent topic in any other tenant. With the default authorization provider, these operations require the tenant admin role for the user's own tenant. The user does not need any permission on the source topic, its namespace or its tenant. This impact analysis assumes that Pulsar has been configured with the default authorization provider. For custom authorization providers, the impact could be different. The user can then consume from the shadow topic, using only permissions on their own topic, and receive retained messages that were published to the source topic in the other tenant. Exposure is limited to messages that are still retained and readable in the source topic's ledgers; messages protected with client-side end-to-end encryption cannot be decrypted without the encryption keys. A producer on the shadow topic can also register a new schema version under the source topic's schema, subject to the schema compatibility settings; existing schema versions are not replaced. In addition, the shadow topic's managed ledger applies its own retention, trimming, offloading and deletion to the source topic's ledgers. This can permanently delete the source topic's ledger data from BookKeeper and from tiered storage, regardless of the source topic's own subscriptions and retention policy, including messages that have not yet been acknowledged. Deleting the shadow topic can also delete the source topic's ledgers. This data loss can also affect shadow topics that were configured intentionally by administrators. This issue affects Apache Pulsar versions from 3.0.0 before 4.0.14 and from 4.1.0 before 4.2.5. Apache Pulsar 2.x releases do not contain the shadow topic implementation. - 4.0.x version users should upgrade to at least 4.0.14. - 4.1.x and 4.2.x version users should upgrade to at least 4.2.5. Users operating versions prior to those listed above should upgrade to the aforementioned patched versions or newer versions. The currently supported Apache Pulsar release lines are 4.0.x and 5.0.x. The supported versions schedule is available at https://pulsar.apache.org/contribute/release-policy/. In the fixed versions, shadow topics are disabled by default and are controlled by the new broker configuration setting enableShadowTopics (default false). While it is disabled, the broker rejects creating shadow topics, setting the PULSAR.SHADOW_SOURCE property, and loading or replicating to existing shadow topics. Deployments that use shadow topics must set enableShadowTopics=true in the broker configuration of all brokers after upgrading; otherwise existing shadow topics will not be loaded. When shadow topics are enabled, binding a shadow topic to a source topic in a different tenant requires the superuser role. The fixed versions also prevent a shadow topic from deleting or trimming the ledgers and offloaded data of its source topic. Affected versions provide no configuration option to disable shadow topics. Users who cannot upgrade immediately can reduce exposure by granting the tenant admin role only to trusted principals.
CVE-2026-105936 1 Apache 1 Pulsar 2026-10-23 N/A
The Pulsar Functions worker REST API provides two endpoints that return the catalog of Pulsar IO connectors installed on the functions worker: the worker connectors endpoint (/admin/v2/worker/connectors) and the deprecated functions connectors endpoint (/admin/v2/functions/connectors and /admin/v3/functions/connectors). When authorization is enabled, the worker connectors endpoint requires super-user access. The functions connectors endpoint, served both by the functions worker and by a broker running the functions worker, returns the same catalog without this check. As a result, when authentication and authorization are enabled, any authenticated client can read the connector catalog through the functions connectors endpoint, regardless of the permissions granted to its role and without super-user access. Unauthenticated requests are rejected unless anonymous access is configured with an anonymous user role. The catalog contains the connector type definitions installed in the functions worker's connectors directory: the connector name, its description, and the source, sink and configuration class names. It does not contain configured source or sink instances, their configuration values or credentials, and an installed connector type does not indicate that a connector is configured or running. The impact is limited to disclosure of this metadata, which can include the names and descriptions of custom connectors installed by the operator. The issue does not allow modifying the catalog or managing connectors. Connector definitions that have a source or sink class are also returned by the built-in sources and sinks endpoints to authenticated clients. In fixed versions, the functions connectors endpoint applies the same checks as the worker connectors endpoint, so that it requires super-user access when authorization is enabled. Clients that are not super-users can use the built-in sources and sinks endpoints to list the available connector types. This issue affects Apache Pulsar versions from 2.4.1 before 4.0.14 and from 4.1.0 before 4.2.5. - 4.0.x version users should upgrade to at least 4.0.14. - 4.1.x and 4.2.x version users should upgrade to at least 4.2.5. Users operating versions prior to those listed above should upgrade to the aforementioned patched versions or newer versions. The currently supported Apache Pulsar release lines are 4.0.x and 5.0.x. The supported versions schedule is available at https://pulsar.apache.org/contribute/release-policy/.
CVE-2026-105935 1 Apache 1 Pulsar 2026-10-23 N/A
The Pulsar Functions Worker provides a REST API endpoint for triggering a function, which publishes a caller-supplied value to one of the function's configured input topics. The Functions Worker performs this publish with its own broker client, which authenticates with the Worker's configured broker-client credentials rather than the credentials of the API caller. When authorization is enabled, in Apache Pulsar 2.4.0 and later versions, the trigger endpoint checks only that the caller is authorized to perform function operations in the function's namespace. It does not check that the caller is authorized to produce to the input topic that the message is published to. Versions before 2.4.0 do not perform a caller authorization check for the trigger endpoint at all. Function input topics are not restricted to the function's own tenant or namespace, and registering a function does not require produce permission on its input topics. As a result, an authenticated user who is authorized to manage functions in a namespace, for example a role granted the functions permission on that namespace, can cause the Functions Worker to publish messages with caller-controlled content to a topic that the user is not authorized to produce to, including topics in other tenants. These messages are published under the identity of the Functions Worker. The issue does not require any function instance to be running or any function code to be executed. It requires that the Functions Worker's broker-client identity is itself authorized to produce to the target topic and, in Apache Pulsar 2.3.0 and later versions, to list the subscriptions of the target topic, as is the case when that identity is a superuser. The impact is on the integrity of the data in the affected topics: consumers of those topics may receive messages from a user who is not permitted to publish them. This concerns the Functions Worker REST API as called by an external, authenticated client; it does not change the security model for function code, which must be fully trusted. In fixed versions, when authorization is enabled, triggering a function additionally requires the caller to be authorized to produce to the selected input topic before any message is published. This issue affects Apache Pulsar versions from 2.0.0-rc1-incubating before 4.0.14 and from 4.1.0 before 4.2.5. - 4.0.x version users should upgrade to at least 4.0.14. - 4.1.x and 4.2.x version users should upgrade to at least 4.2.5. Users operating versions prior to those listed above should upgrade to the aforementioned patched versions or newer versions. The currently supported Apache Pulsar release lines are 4.0.x and 5.0.x. The supported versions schedule is available at https://pulsar.apache.org/contribute/release-policy/. Users of Apache Pulsar 2.4.0 and later versions with authorization enabled who cannot upgrade immediately can limit the permission to manage functions to trusted roles. Users of versions before 2.4.0 should restrict access to the Functions Worker REST API to trusted callers, because in these versions the trigger endpoint does not check the caller's permission to manage functions.
CVE-2026-105934 1 Apache 1 Pulsar 2026-10-23 N/A
The Apache Pulsar broker admin REST API provides a truncate operation for persistent topics (DELETE /admin/v2/persistent/{tenant}/{namespace}/{topic}/truncate). Truncating a topic moves all subscription cursors of the topic to the end of the topic and deletes the topic's inactive ledgers. Truncating a non-partitioned topic, or a single partition addressed by its partition name, correctly requires the tenant admin role or the superuser role. When the operation is requested for the name of a partitioned topic, the broker does not apply this tenant admin check to the caller. Instead, it truncates each partition using the broker's own internal admin client, which authenticates with the broker's configured client credentials rather than the caller's identity. Each per-partition truncate request is still checked for the tenant admin role or the superuser role, but against the broker's internal identity instead of the caller. The partitions are therefore truncated only when the broker's configured client role is a superuser or an admin of the target tenant, which is the usual configuration when authorization is enabled. As a result, when that condition holds, an authenticated user who is not a tenant admin can truncate any partitioned topic on which the user has lookup permission. Caller authentication and lookup permission alone are not sufficient: if the broker's internal identity lacks tenant admin or superuser authorization for the target tenant, the per-partition requests are rejected. With the default authorization provider, lookup permission is granted by produce or consume permission on the topic or its namespace. A user with no permissions on the topic cannot trigger the issue. This impact analysis assumes that Pulsar has been configured with the default authorization provider. For custom authorization providers, the impact could be different. Truncating a partitioned topic this way moves the cursors of all subscriptions on every partition to the end of the topic, so any unacknowledged backlog is skipped and is no longer delivered to consumers. It also deletes eligible older ledgers of each partition regardless of the namespace's configured retention policy, so messages stored in those ledgers can be permanently lost. The ledger currently being written is not deleted by the truncate operation. The issue does not allow reading message contents or changing permissions or configuration, and it does not give access to topics on which the user has no lookup permission. This issue affects Apache Pulsar versions from 2.8.0 before 4.0.14 and from 4.1.0 before 4.2.5. - 4.0.x version users should upgrade to at least 4.0.14. - 4.1.x and 4.2.x version users should upgrade to at least 4.2.5. Users operating versions prior to those listed above should upgrade to the aforementioned patched versions or newer versions. The currently supported Apache Pulsar release lines are 4.0.x and 5.0.x. The supported versions schedule is available at https://pulsar.apache.org/contribute/release-policy/. Users who cannot upgrade immediately can reduce exposure by restricting network access to the broker's admin REST API (/admin/v2) to trusted administrative clients.
CVE-2026-109296 1 Openwebui 1 Open Webui 2026-10-23 4.3 Medium
Open WebUI before 0.11.4 contains a missing authorization vulnerability that allows authenticated users to reach disabled model provider backends by supplying an explicit backend index. Attackers can pass the index as a path segment or query parameter on Ollama and OpenAI-compatible listing routes to trigger requests carrying configured API keys, read version strings, and enumerate connections.
CVE-2026-109287 2 Open-webui, Openwebui 2 Open-webui, Open Webui 2026-10-23 4.3 Medium
Open WebUI from 0.9.6 before 0.11.4 contains an authorization flaw where the knowledge base file listing does not verify that a supplied directory_id belongs to the requested knowledge base. Users with read access to any knowledge base can supply a retained foreign directory UUID to GET /api/v1/knowledge/{id}/files. The returned breadcrumbs expose folder names, owner user ids and knowledge base ids of that directory and all its ancestors.
CVE-2026-112342 2026-10-23 7.1 High
Tandoor Recipes before 2.7.0 contains an improper cache-key design in cookbook/helper/permission_helper.py that allows authenticated users to retain stale group-based permissions across different spaces by exploiting a cache key keyed only on user id while omitting the active space, with the cached entry's TTL refreshed on every request. Attackers can create their own space to obtain an admin group designation, then switch their active space to a victim space where they hold lesser privileges, causing the stale cached admin decision to authorize elevated access and bypass group revocations or demotions across multiple permission classes and views.
CVE-2026-115883 2026-10-23 N/A
LangGraph checkpoint savers provide Postgres- and SQLite-backed state persistence for LangGraph workflows and agents. Prior to langgraph-checkpoint-postgres 3.1.3 and langgraph-checkpoint-sqlite 3.1.2, PostgresStore, AsyncPostgresStore, SqliteStore, and AsyncSqliteStore flatten namespace labels with ".".join(namespace), while BaseStore validates labels only for put and aput. Unvalidated dotted labels passed through get, search, delete, list_namespaces, their asynchronous equivalents, or direct batch and abatch operations can resolve to another tenant's stored namespace, allowing cross-namespace reads, overwrites, or deletion. InMemoryStore is not affected because it compares namespace tuples. This issue is fixed in langgraph-checkpoint-postgres 3.1.3 and langgraph-checkpoint-sqlite 3.1.2.
CVE-2026-111352 1 Thinkcmf 1 Thinkcmf 2026-10-23 8.8 High
ThinkCMF through 8.0.1 contains an incorrect authorization vulnerability in RestAdminBaseController that allows restricted backend administrators to call every admin REST API endpoint because Auth::check() fails open when no admin_api rule exists. Attackers with a valid admin-type API token can list member emails and mobile numbers, disable members, and call PUT admin/roles/{id}/authorize to grant themselves full administrator rights.
CVE-2026-111332 2026-10-23 3.7 Low
OxiCloud 0.9.1 through 0.9.3 contains an incorrect authorization vulnerability that allows anonymous visitors to keep share access after password protection is added. Attackers holding an existing oxi_shares share-ring cookie can request content via GET /api/files/{id} to read shared files or folder contents despite the new password.
CVE-2026-56826 1 Shopperlabs 1 Shopper 2026-10-23 5.4 Medium
Shopper is a Headless e-commerce Admin Panel. From 2.0.0 until 2.9.2, authenticated users who could reach the Settings pages with only access_setting could directly invoke destructive actions through the Livewire endpoint because packages/admin/src/Livewire/Components/Settings/Zones/ZoneShippingOptions.php, packages/admin/src/Livewire/Components/Settings/Zones/Detail.php, packages/admin/src/Livewire/Components/Settings/Taxes/Detail.php, and packages/admin/src/Livewire/Components/Settings/Taxes/TaxRates.php did not enforce server-side delete authorization. The actions could delete carrier options, shipping zones, tax zones, and tax rates, disrupting checkout shipping, payment-method mapping, and tax calculation. This issue is fixed in version 2.9.2.
