**Name of the Vulnerable Software and Affected Versions** OpenClaw versions prior to 2026.6.6 **Description** An environment variable filtering issue exists in the host exec component that fails to properly sanitize `rustup` startup variables. This allows attackers with lower-trust caller access or configured input paths to execute or persist actions beyond their intended authorization level. **Recommendations** Update to version 2026.6.6.

Name of the Vulnerable Software and Affected Versions OpenClaw versions prior to 2026.3.22 Description OpenClaw contains an unauthenticated resource exhaustion issue in how it handles voice call webhooks. The system buffers request bodies before verifying the provider's signature, allowing attackers to send large or malicious requests to deplete server resources without authentication, effectively bypassing signature validation. Recommendations Update to version 2026.3.22 or later.
