Summary
OpenClaw's SSRF IP classifier did not treat IPv6 multicast literals (
ff00::/8) as blocked/private-internal. This allowed literal multicast hosts to pass SSRF preflight checks.Impact
A bypass in address classification existed for IPv6 multicast literals. OpenClaw's network fetch/navigation paths are constrained to HTTP/HTTPS and this was triaged as low-severity defense-in-depth hardening.
