Summary

Duplicate Advisory: OpenClaw: Gemini OAuth exposed the PKCE verifier through the OAuth state parameter

Details

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-9jpj-g8vv-j5mf. This link is maintained to preserve external references.

Original Description

OpenClaw before 2026.4.2 reuses the PKCE verifier as the OAuth state parameter in the Gemini OAuth flow, exposing it through the redirect URL. Attackers who capture the redirect URL can obtain both the authorization code and PKCE verifier, defeating PKCE protection and enabling token redemption.
