OpenClaw < 2026.2.12 - Path Traversal via Unsanitized sessionId and sessionFile Parameters

Published Mar 5, 2026

Modified Yesterday

Details

OpenClaw versions prior to 2026.2.12 construct transcript file paths using unsanitized sessionId parameters and sessionFile paths without enforcing directory containment. Authenticated attackers can exploit path traversal sequences like ../../etc/passwd in sessionId or sessionFile parameters to read or write arbitrary files outside the agent sessions directory.
