Summary
## Summary The SSRF/IP classifier treated several IPv6 special-use ranges as public and allowed fetches to proceed. ## Impact An attacker who controlled a fetched URL could target internal or non-routable IPv6 addresses that should have been blocked by the SSRF guard. ## Affected Component `src/shared/net/ip.ts, src/infra/net/ssrf.*` ## Fixed Versions - Affected: `<= 2026.3.24` - Patched: `>= 2026.3.28` - Latest stable `2026.3.28` contains the fix. ## Fix Fixed by commit `d61f8e5672` (`Net: block missing IPv6 special-use ranges`). OpenClaw thanks @nicky-cc of Tencent zhuque Lab [https://github.com/Tencent/AI-Infra-Guard](https://github.com/Tencent/AI-Infra-Guard) for reporting.
