CVE-2026-41361 — OpenClaw < 2026.3.28 - SSRF Guard Bypass via IPv6 Special-Use Ranges

Affected: OpenClaw

OpenClaw before 2026.3.28 contains an SSRF guard bypass vulnerability that fails to block four IPv6 special-use ranges. Attackers can exploit this by crafting URLs targeting internal or non-routable IPv6 addresses to bypass SSRF protections.

GHSA-g86v-f9qv-rh6m — OpenClaw SSRF guard misses four IPv6 special-use ranges

Affected: npm: openclaw

## 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`).
