How to Fix GHSA-8cp7-rp8r-mg77

To remediate this vulnerability, upgrade all affected Openclaw dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

openclaw fixed: 2026.2.19
npm install openclaw@2026.2.19
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release:

npm ls openclaw

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-8cp7-rp8r-mg77, inspect your project dependencies using npm:

npm ls openclaw

Analyze the terminal output to locate any version of Openclaw in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2026.2.19), your application is affected.

Note: The npm ls openclaw command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-918: Server-Side Request Forgery (SSRF), where the web server receives a url or similar request from an upstream component and retrieves the contents of this url, but it does not sufficiently ensure that the request is being sent to the expected destination. In Openclaw, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

## 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. ## Fix Commit(s) - `d51929ecb52fe65e90bf36795f4247feb29eb8aa` OpenClaw thanks @zpbrent for reporting.
