OpenClaw's unsanitized session ID enables path traversal in transcript file operations
OpenClaw versions <= 2026.2.9 construct transcript file paths using an unsanitized sessionId and also accept sessionFile paths without enforcing that they stay within the agent sessions directory. A crafted sessionId and/or sessionFile (example: ../../etc/passwd) can cause path traversal when the gateway performs transcript file read/write operations. Preconditions: an attacker must be able to authenticate to the gateway (gateway token/password). By default the gateway binds to loopback (local-only); configurations that expose …
