CVE-2026-35636

EUVD-2026-21128
OpenClaw versions 2026.3.11 through 2026.3.24 contain a session isolation bypass vulnerability where session_status resolves sessionId to canonical session keys before enforcing visibility checks. Sandboxed child sessions can exploit this to access parent or sibling sessions that should be blocked by explicit sessionKey restrictions.
