Name of the Vulnerable Software and Affected Versions OpenClaw versions 2026.3.11 through 2026.3.24

Description OpenClaw versions 2026.3.11 through 2026.3.24 contain a session isolation bypass. The session status function resolves sessionId to canonical session keys before enforcing visibility checks. This allows sandboxed child sessions to access parent or sibling sessions that should be blocked by explicit sessionKey restrictions.

Recommendations Update to a version later than 2026.3.24.
