OpenClaw: SSRF via Unguarded Configured Base URLs in Multiple Channel Extensions (Incomplete Fix for CVE-2026-28476)
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`. ## Fix Commit(s) - `f92c92515bd439a71bd03eb1bc969c1964f17acf`
