phpMyFAQ - Insufficient Authorization Check in Admin API Endpoints
Summary
phpMyFAQ before 4.1.2 contains an insufficient authorization vulnerability in admin-api routes that allows authenticated ordinary users to access administrative endpoints by only checking login status instead of verifying backend privileges. Attackers with valid frontend user accounts can access sensitive backend operational information including dashboard versions, LDAP configuration, Elasticsearch statistics, and health-check data.

Title
RustFS: UploadPartCopy Does Not Enforce Destination Bucket Policy on Copy Source
Summary
RustFS is a distributed object storage system built in Rust. Prior to 1.0.0-beta.2, improper authorization in the UploadPartCopy operation allows copying objects across buckets without enforcing destination bucket restrictions on allowed copy sources. The implementation validates GetObject permission on the source bucket and PutObject on the destination bucket independently, but does not enforce any policy constraints on whether the destination bucket permits the specified copy source. This enables unauthorized cross-bucket data movement. This vulnerability is fixed in 1.0.0-beta.2.

Title
Himmelblau: Authentication Bypass via Cross-User Local Session Impersonation in Device Authorization Grant (DAG) Flow
Summary
Himmelblau is an interoperability suite for Microsoft Azure Entra ID and Intune. From 2.0.0 to before 3.1.5 and 2.3.11, Himmelblau contained an authentication bypass vulnerability in the Device Authorization Grant (DAG) flow that allowed a user within the same Entra ID domain to obtain a local Unix session as another user by providing their own valid credentials. The vulnerability existed in the token_validate function, which validated domain aliases for legitimate multi-domain scenarios but failed to verify that the local part (username) of the authenticated user's UPN matched the requested account username. The function only compared domains, not the complete usernames. This vulnerability is fixed in 3.1.5 and 2.3.11.

Title
Heym < 0.0.21 Authorization Bypass in Workflow Execution
Summary
Heym before 0.0.21 contains an authorization bypass vulnerability in workflow execution that allows authenticated users to execute arbitrary workflows by referencing victim workflow UUIDs without proper access validation. Attackers can create workflows with execute nodes or agent subWorkflowIds pointing to victim workflow UUIDs to load and execute those workflows under attacker-controlled execution paths, exposing victim workflow outputs and triggering workflow nodes with unintended side effects.

Title
Cross-tenant IDOR on feature-flag and assist-stats routes via {project_id} case mismatch
Summary
OpenReplay is a self-hosted session replay suite. Prior to 1.26.0, there is a cross-tenant IDOR on feature-flag and assist-stats routes via {project_id} case mismatch. ProjectAuthorizer.__call__ (OSS api/auth/auth_project.py:14-38 and EE ee/api/auth/auth_project.py:14-46) only runs projects.is_authorized(project_id, tenant_id, user_id) + projects.get_project(tenant_id, project_id) when self.project_identifier == "projectId" (camelCase). For EE multi-tenant, feature-flag queries only filter on project_id, never tenant_id. Any authenticated user in tenant A can read/update/delete feature-flag rows belonging to tenant B by iterating the sequential integer project_id + feature_flag_id. OSS is single-tenant by design ({"errors":["tenants already registered"]} on second signup) so there's no cross-tenant impact This vulnerability is fixed in 1.26.0.

Title
Open WebUI: Read-Only Users Can Toggle Note Pin Status via Incorrect Permission Check (Write via Read-Only Access)
Summary
Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.9.3, the POST /api/v1/notes/{id}/pin endpoint performs a write operation (toggling the is_pinned field) but only checks for read permission. Users with read-only access to a shared note can pin/unpin it, which is a state-modifying action that should require write permission. This vulnerability is fixed in 0.9.3.

CVE-2026-45339 (GCVE-0-2026-45339)

Title
Open WebUI: API key endpoint restrictions bypassed via `x-api-key` header — full message processing on restricted endpoints
Summary
Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.9.0, Open WebUI allows admins to restrict which API endpoints an API key can access. When an API key is restricted from /api/v1/messages, requests using the Authorization: Bearer sk-... header are correctly blocked with 403. However, the same key sent via the x-api-key header bypasses the restriction entirely — the request is authenticated, the model is invoked, and a full response is returned. This vulnerability is fixed in 0.9.0.

Mitigation
Phase: Architecture and Design
Description:
- Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) [REF-229] to enforce the roles at the appropriate boundaries.
- Note that this approach may not protect against horizontal authorization, i.e., it will not protect a user from attacking others with the same role.
Mitigation
Phase: Architecture and Design
Description:
- Ensure that access control checks are performed related to the business logic. These checks may be different than the access control checks that are applied to more generic resources such as files, connections, processes, memory, and database records. For example, a database may restrict access for medical records to a specific database user, but each record might only be intended to be accessible to the patient and the patient's doctor [REF-7].
Mitigation ID: MIT-4.4
Phase: Architecture and Design
Strategy: Libraries or Frameworks
Description:
- Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
- For example, consider using authorization frameworks such as the JAAS Authorization Framework [REF-233] and the OWASP ESAPI Access Control feature [REF-45].
Mitigation
Phase: Architecture and Design
Description:
- For web applications, make sure that the access control mechanism is enforced correctly at the server side on every page. Users should not be able to access any unauthorized functionality or information by simply requesting direct access to that page.
- One way to do this is to ensure that all pages containing sensitive information are not cached, and that all such pages restrict access to requests that are accompanied by an active and authenticated session token associated with a user who has the required permissions to access that page.
Mitigation
Phases: System Configuration, Installation
Description:
- Use the access control capabilities of your operating system and server environment and define your access control lists accordingly. Use a "default deny" policy when defining these ACLs.
