Description

Summary

SSRF via Unguarded Configured Base URLs in Multiple Channel Extensions (Incomplete Fix for CVE-2026-28476)

Affected Packages / Versions

  • Package: openclaw
  • Affected versions: <= 2026.3.24
  • First patched version: 2026.3.25
  • Latest published npm version at verification time: 2026.3.24

Details

Several channel extensions still used raw fetch() against configured base URLs without the SSRF guard that was added for CVE-2026-28476. Commit f92c92515bd439a71bd03eb1bc969c1964f17acf routes those outbound requests through fetchWithSsrFGuard so configured endpoints cannot be rebound to blocked internal destinations.

Verified vulnerable on tag v2026.3.24 and fixed on main by commit f92c92515bd439a71bd03eb1bc969c1964f17acf.
