NVD description
OpenClaw versions prior to 2026.2.12 fail to validate the sessionFile path parameter, allowing authenticated gateway clients to write transcript data to arbitrary locations on the host filesystem. Attackers can supply a sessionFile path outside the sessions directory to create files and append data repeatedly, potentially causing configuration corruption or denial of service.
What to do
- Upgrade OpenClaw to
2026.2.12or later. - Do not expose the component's API or UI to the internet without authentication in front of it.
