Summary OpenClaw hardened cron webhook delivery against SSRF ## Affected Packages / Versions - `openclaw` npm package versions `<= 2026.2.17`. ## Vulnerability Cron webhook delivery in `src/gateway/server-cron.ts` used `fetch()` directly, so webhook targets could reach private/metadata/internal endpoints without SSRF policy checks. ## Fix Commit(s) - `99db4d13e` - `35851cdaf` Thanks @Adam55A-code for reporting.
