Summary
OpenClaw: macOS beta onboarding exposed PKCE verifier via OAuth state
The affected surface is the OpenClaw macOS app onboarding flow, and the macOS app is currently in beta.
In that beta onboarding flow, Anthropic OAuth used the PKCE code_verifier value as OAuth state, exposing that secret in front-channel URL state.

Impact
Scope is limited to the macOS beta onboarding OAuth path. Exploitation required obtaining both OAuth authorization artifacts and exposed state values during that flow.

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.

OpenClaw removed Anthropic OAuth sign-in from macOS onboarding and now supports setup-token-only Anthropic subscription auth in this path.
Frequently Asked Questions
- What is GHSA-6G25-PC82-VFWP? GHSA-6G25-PC82-VFWP is a medium-severity security vulnerability in openclaw (npm), affecting versions <= 2026.2.24. It is fixed in 2026.2.25.
- Which versions of openclaw are affected by GHSA-6G25-PC82-VFWP? openclaw (npm) versions <= 2026.2.24 is affected.
- Is there a fix for GHSA-6G25-PC82-VFWP? Yes. GHSA-6G25-PC82-VFWP is fixed in 2026.2.25. Upgrade to this version or later.
- Is GHSA-6G25-PC82-VFWP exploitable, and should I be worried? Whether GHSA-6G25-PC82-VFWP 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-6G25-PC82-VFWP 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.
