Summary
OpenClaw: message.action forwarding could send Gateway credentials to model-supplied loopback URLs
message.action forwarding could send Gateway credentials to model-supplied loopback URLs. In affected versions, model-controlled action metadata that selects a loopback Gateway URL could forward the action payload with Gateway credentials to the supplied loopback URL.
This advisory is scoped to the named feature and configuration. It does not change OpenClaw's trusted-operator model: authenticated Gateway operators, installed plugins, and intentional local execution surfaces remain trusted unless a separate policy, approval, allowlist, sandbox, or auth boundary is crossed.
Patched Versions
The first stable patched version is 2026.5.2.
Mitigations
restrict message action forwarding and avoid model-supplied loopback targets until patched. As general hardening, keep channel and tool allowlists narrow, avoid sharing one Gateway between mutually untrusted users, and disable the affected feature when it is not needed.
Impact
When the affected feature is enabled and reachable, this could expose the token and action payload to a local listener chosen through the affected path. Practical impact depends on the operator's configuration and whether lower-trust input can reach that path.

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.

Frequently Asked Questions
- What is GHSA-GRC3-2J34-P6GM? GHSA-GRC3-2J34-P6GM is a medium-severity security vulnerability in openclaw (npm), affecting versions <= 2026.4.29. It is fixed in 2026.5.2.
- Which versions of openclaw are affected by GHSA-GRC3-2J34-P6GM? openclaw (npm) versions <= 2026.4.29 is affected.
- Is there a fix for GHSA-GRC3-2J34-P6GM? Yes. GHSA-GRC3-2J34-P6GM is fixed in 2026.5.2. Upgrade to this version or later.
- Is GHSA-GRC3-2J34-P6GM exploitable, and should I be worried? Whether GHSA-GRC3-2J34-P6GM 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-GRC3-2J34-P6GM 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.
