Name of the Vulnerable Software and Affected Versions OpenClaw versions prior to 2026.2.12

Description OpenClaw versions prior to 2026.2.12 do not properly validate the sessionFile path parameter, potentially allowing authenticated gateway clients to write transcript data to arbitrary locations on the host filesystem. An attacker can supply a sessionFile path outside the sessions directory to create files and repeatedly append data, which could lead to configuration corruption or denial of service. The issue involves the gateway accepting an untrusted sessionFile path when resolving the session transcript file.

Recommendations Update OpenClaw to version 2026.2.12 or later.
