OpenClaw (formerly Moltbot or Clawdbot) vulnerability analysis and mitigation
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.
