NVD description
OpenClaw versions prior to 2026.3.2 contain a vulnerability in the stageSandboxMedia function in which it fails to validate destination symlinks during media staging, allowing writes to follow symlinks outside the sandbox workspace. Attackers can exploit this by placing symlinks in the media/inbound directory to overwrite arbitrary files on the host system outside sandbox boundaries.
What to do
- Upgrade OpenClaw to
2026.3.2or later. - Do not expose the component's API or UI to the internet without authentication in front of it.
