Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for openclaw. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

How do I mitigate GHSA-9jpj-g8vv-j5mf if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

How does O3 Security protect against GHSA-9jpj-g8vv-j5mf?

O3 pinpoints whether GHSA-9jpj-g8vv-j5mf is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is GHSA-9jpj-g8vv-j5mf actively exploited in the wild?

No public exploit code has been indexed for GHSA-9jpj-g8vv-j5mf yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

Description

Summary

Before OpenClaw 2026.4.2, the Gemini OAuth flow reused the PKCE verifier as the OAuth state value. Because the provider reflected state back in the redirect URL, the verifier could be exposed alongside the authorization code.

Impact

Anyone who could capture the redirect URL could learn both the authorization code and the PKCE verifier, defeating PKCE's interception protection for that flow and enabling token redemption.

Affected Packages / Versions

Package: openclaw (npm)
Affected versions: <= 2026.4.1
