NVD description
OpenClaw versions prior to 2026.2.19 tools.exec.safeBins contains an input validation bypass vulnerability that allows attackers to execute unintended filesystem operations through sort output flags or recursive grep flags. Attackers with command execution access can leverage sort -o flag for arbitrary file writes or grep -R flag for recursive file reads, circumventing intended stdin-only restrictions.
What to do
- Upgrade OpenClaw to
2026.2.19or later. - Do not expose the component's API or UI to the internet without authentication in front of it.
