Summary

OpenClaw versions prior to 2026.2.25 contain a time-of-check-time-of-use vulnerability in approval-bound system.run execution where the cwd parameter is validated at approval time but resolved at execution time.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
