Description

Summary

OpenClaw's SSRF hostname/IP guard did not detect ISATAP embedded IPv4 addresses (...:5efe:w.x.y.z). A crafted URL containing an ISATAP IPv6 literal could embed a private IPv4 target (for example loopback) and bypass private-address filtering in URL-fetching paths.

Severity Assessment

Rated medium: the bug weakens SSRF protections in URL fetch flows, but impact depends on reaching a URL-fetching path with attacker-controlled input and is generally constrained to internal network access attempts.

Affected Packages / Versions

  • Package: openclaw (npm)
  • Affected: >=2026.1.20 <=2026.2.17
  • Latest published at patch time: 2026.2.17
  • Patched release: 2026.2.19

Security Policy Context

Per SECURITY.md, OpenClaw's web/gateway surface is intended for local use by default, public internet exposure is out-of-scope, and prompt-injection reports are out-of-scope for bounty handling. This advisory tracks a core SSRF-guard bypass in fetch protections.

Impact

This can permit SSRF-style access attempts to internal/private network targets through URL ingestion/fetch paths that rely on shared hostname/IP blocking.

Fix

  • Added RFC 5214 ISATAP embedded-IPv4 detection to the shared SSRF classifier.
  • Centralized hostname/IP blocking through isBlockedHostnameOrIp and routed relevant validators to that shared path.
  • Added regression tests for ISATAP private vs public embedded IPv4 handling.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for openclaw, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update openclaw to 2026.2.19 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-8cp7-rp8r-mg77 is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

  4. How O3 protects you

    O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-8cp7-rp8r-mg77 can be triaged on real exposure rather than presence alone.

Tailored to GHSA-8cp7-rp8r-mg77. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
