**Name of the Vulnerable Software and Affected Versions** Plane versions prior to 1.4.0 **Description** An authentication bypass allows any authenticated workspace member, including guests with limited access, to retrieve records from every project within a workspace. This occurs because the system fails to verify if the requester belongs to the specific project being accessed. An attacker can enumerate names, descriptions, sprint dates, issue counts, progress snapshots, external integration IDs, linked URLs, and member lists for cycles and modules in private projects via the following endpoints: - '/api/workspaces/{slug}/cycles/' through WorkspaceCyclesEndpoint - '/api/workspaces/{slug}/modules/' through WorkspaceModulesEndpoint **Recommendations** Update to version 1.4.0.

**Name of the Vulnerable Software and Affected Versions** SigNoz versions 0.87.0 through 0.141.0 **Description** Authenticated users with a Viewer role or higher can perform SQL injection by providing specially crafted telemetry field-key names. The application fails to properly escape these names in the 'v5 query range' API endpoint, allowing attackers to use backticks and quotes to break out of identifiers and string literals. This enables the execution of arbitrary ClickHouse SQL commands to access system tables and exfiltrate data. **Recommendations** Update SigNoz to version 0.142.0 or later.
