Title
n8n: Per-Resource OAuth Consent Bypass via Unbound Refresh Token Resource Substitution
Summary
n8n is an open source workflow automation platform. Prior to 2.37.7 and 2.38.1, the OAuth token endpoint bound an authorization code's first access token to the consented resource but did not bind its refresh token. Refreshing checked only that the requested resource was registered, not that it matched the original grant. An OAuth client approved for one workflow could substitute a different workflow URL in the resource parameter and obtain a valid token for an unapproved workflow accessible to the consenting user. This issue is fixed in versions 2.37.7 and 2.38.1.

Title
Unauthenticated Remote Code Execution in Akana API Platform
Summary
An unauthenticated remote code execution vulnerability exists in the Policy Manager console of Akana API Platform. A path normalization discrepancy between the authentication filter and the servlet dispatcher allows a crafted request to bypass authentication and reach an endpoint that evaluates attacker-supplied script code without sandboxing, resulting in arbitrary code execution. Exploitation requires no authentication or user interaction.

Title
AppFlowy-Cloud through 0.9.64 Cross-Workspace Collab Read via WebSocket
Summary
AppFlowy-Cloud through 0.9.64 fails to validate workspace membership when establishing WebSocket connections in the establish_ws_connection_v2 handler, allowing authenticated users to bind sessions to workspaces they do not belong to. Attackers can send sync Manifest messages with victim object identifiers to read full document or database state from collaborations in other workspaces without victim involvement.

Title
Postgres MCP Pro 0.3.0 Restricted-Mode Bypass via FROM-Clause Function
Summary
Postgres MCP Pro 0.3.0 contains a restricted-mode bypass vulnerability where function-name validation is not applied to RangeFunction nodes in FROM clauses. Attackers can execute file-reading functions like pg_read_file through FROM-clause syntax to read arbitrary files despite restricted-mode protections.

Summary
AppFlowy-Cloud 0.9.64 fails to verify that requested collab objects belong to the workspace in authorization checks, allowing attackers to access documents and database rows across workspaces. Attackers can supply a victim's object ID with their own workspace ID to bypass access controls and read, modify, or delete cross-workspace data.

Traefik before v2.11.55 and v3.0.0 through v3.7.10 mTLS Bypass via TLS Option Conflict
Summary
Traefik before v2.11.55 and v3.0.0 through v3.7.10 contain a TLS option conflict resolution vulnerability that allows unauthenticated attackers to bypass client-certificate authentication by creating conflicting TLS options on multi-host routers. Attackers can reach protected backends by exploiting shared TLS resolution across multiple hostnames in a single router rule, causing the strict mTLS requirement to fall back to default options for all hosts.

Mitigation
Architecture and Design
- 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
Architecture and Design
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].

Architecture and Design
Strategy: Libraries or Frameworks
- 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
Architecture and Design
- 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
System Configuration
Installation
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.
