GHSA-g86v-f9qv-rh6m: OpenClaw SSRF guard misses four IPv6 special-use ranges
Summary
OpenClaw had a vulnerability in its SSRF guard (a security check that blocks requests to internal network addresses), which incorrectly classified certain IPv6 special-use ranges (reserved address groups in the newer internet protocol) as public. This allowed attackers to potentially access internal or non-routable addresses that should have been blocked.
Solution / Mitigation
Update OpenClaw to version 2026.3.28 or later. The fix was implemented in commit d61f8e5672 with the change "Net: block missing IPv6 special-use ranges."
