GHSA-56F2-HVWG-5743

A server-side request forgery (SSRF) vulnerability in the Image tool allowed attackers to force OpenClaw to make HTTP requests to arbitrary internal or restricted network targets.

Affected Versions

• npm: openclaw <= 2026.2.1

Patched Versions

• npm: openclaw 2026.2.2 and later

Fix Commits

• 81c68f582d4a9a20d9cca9f367d2da9edc5a65ae (guard remote media fetches with SSRF checks)
• 9bd64c8a1f91dda602afc1d5246a2ff2be164647 (expand SSRF guard coverage)

Details

The Image tool accepts file paths, file:// URLs, data: URLs, and http(s) URLs. In vulnerable versions, http(s) URLs were fetched without SSRF protections, enabling requests to localhost, RFC1918, link-local, and cloud metadata targets.

This was fixed by routing remote media fetching through the SSRF guard (private/internal IP + hostname blocking, redirect hardening, DNS pinning).

Exploitability Notes

• Requires attacker-controlled invocation of the Image tool (direct tool access, or a gateway/channel surface that forwards untrusted image arguments into tool calls).
• The image tool expects the fetched content to be an image. Many high-value SSRF targets return text/JSON (for example cloud metadata endpoints), which will typically fail media-type validation. In practice, the most direct confidentiality impact comes from internal endpoints that actually return images (screenshots/renderers, camera snapshots, chart exports, etc.).
• Remote fetches are GET-only with no custom headers. Some metadata services require special headers or session tokens (for example GCP Metadata-Flavor, AWS IMDSv2 token), which can further reduce the likelihood of direct credential theft in some environments.
• Despite the above constraints, SSRF remains a powerful primitive: it can enable internal network probing and access to unauthenticated/internal HTTP endpoints, and can chain with other weaknesses if present.

Thanks @p80n-sec for reporting.

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.

GHSA-56F2-HVWG-5743 has a CVSS score of 7.6 (High). The vector is network-reachable, low privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (2026.2.2); upgrading removes the vulnerable code path.

1. What is GHSA-56F2-HVWG-5743? GHSA-56F2-HVWG-5743 is a high-severity server-side request forgery (SSRF) vulnerability in openclaw (npm), affecting versions < 2026.2.2. It is fixed in 2026.2.2. Untrusted input controls the target URL of a server-initiated request, which may reach internal services not otherwise accessible from outside.
2. How severe is GHSA-56F2-HVWG-5743? GHSA-56F2-HVWG-5743 has a CVSS score of 7.6 (High). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
3. Which versions of openclaw are affected by GHSA-56F2-HVWG-5743? openclaw (npm) versions < 2026.2.2 is affected.
4. Is there a fix for GHSA-56F2-HVWG-5743? Yes. GHSA-56F2-HVWG-5743 is fixed in 2026.2.2. Upgrade to this version or later.
5. Is GHSA-56F2-HVWG-5743 exploitable, and should I be worried? Whether GHSA-56F2-HVWG-5743 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.

6. What actually determines whether GHSA-56F2-HVWG-5743 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.
7. How do I fix GHSA-56F2-HVWG-5743? Upgrade openclaw to 2026.2.2 or later.
