Description

Description

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 the gateway widen the attack surface.

Affected Packages / Versions

  • Package: openclaw (npm)
  • Affected: <= 2026.2.9
  • Fixed: >= 2026.2.12

Fix

Fixed by validating session IDs (rejecting path separators / traversal sequences) and enforcing sessions-directory containment for session transcript file operations.

Mitigation

Upgrade to openclaw >= 2026.2.12.
