Arbitrary file access via transcript path traversal
Published Mar 5, 2026 · Updated Mar 5, 2026
Path traversal in OpenClaw before 2026.2.12 allows remote authenticated users to read or write files outside the sessions directory. Transcript path resolution accepts sessionId separators and sessionFile paths without checking that the normalized result remains under the agent sessions directory. A gateway token or password is required; the default loopback bind limits reachability to the host, while exposed gateways permit remote access.
