Summary
OpenClaw has SSRF guard bypass via IPv6 transition over ISATAP
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.

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.
Untrusted input controls the target URL of a server-initiated request, which may reach internal services not otherwise accessible from outside. Typical impact: access to internal metadata services, internal APIs, or cloud credentials.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

- Added RFC 5214 ISATAP embedded-IPv4 detection to the shared SSRF classifier.
- Centralized hostname/IP blocking through
isBlockedHostnameOrIpand routed relevant validators to that shared path. - Added regression tests for ISATAP private vs public embedded IPv4 handling.
Frequently Asked Questions
- What is GHSA-8CP7-RP8R-MG77? GHSA-8CP7-RP8R-MG77 is a medium-severity server-side request forgery (SSRF) vulnerability in openclaw (npm), affecting versions >= 2026.1.20, < 2026.2.19. It is fixed in 2026.2.19. Untrusted input controls the target URL of a server-initiated request, which may reach internal services not otherwise accessible from outside.
- Which versions of openclaw are affected by GHSA-8CP7-RP8R-MG77? openclaw (npm) versions >= 2026.1.20, < 2026.2.19 is affected.
- Is there a fix for GHSA-8CP7-RP8R-MG77? Yes. GHSA-8CP7-RP8R-MG77 is fixed in 2026.2.19. Upgrade to this version or later.
- Is GHSA-8CP7-RP8R-MG77 exploitable, and should I be worried? Whether GHSA-8CP7-RP8R-MG77 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether GHSA-8CP7-RP8R-MG77 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
