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.

Affected Packages / Versions

  • Package: openclaw (npm)
  • Affected versions: <= 2026.2.24
  • Patched versions: >= 2026.2.25

Technical Details

The IPv6 private/internal range set omitted multicast, so addresses like ff02::1 and ff05::1:3 were not classified as blocked by the shared SSRF classifier.
