Description

Summary

OpenClaw's SSRF protection could be bypassed using full-form IPv4-mapped IPv6 literals such as 0:0:0:0:0:ffff:7f00:1 (which is 127.0.0.1). This could allow requests that should be blocked (loopback / private network / link-local metadata) to pass the SSRF guard.

  • Vulnerable component: SSRF guard (src/infra/net/ssrf.ts)
  • Issue type: SSRF protection bypass

Affected Packages / Versions

  • Package: openclaw (npm)
  • Vulnerable: <= 2026.2.13
  • Patched: >= 2026.2.14 (planned next release)

Details

The SSRF guard's IP classification did not consistently detect private IPv4 addresses when they were embedded in IPv6 using full-form IPv4-mapped IPv6 notation. As a result, inputs like 0:0:0:0:0:ffff:7f00:1 could bypass loopback/private network blocking.

Release Process Note

This advisory is kept in draft state with the patched version set to the planned next release. Once openclaw@2026.2.14 is published to npm, the only remaining step should be to publish this advisory.

Thanks @yueyueL for reporting.
