OpenClaw Chutes manual OAuth state validation bypass can cause credential substitution
Summary
The manual Chutes OAuth login flow could accept attacker-controlled callback input in a way that bypassed OAuth CSRF state validation, potentially resulting in credential substitution.
Impact
If an attacker can convince a user to paste attacker-provided OAuth callback data during the manual login prompt, OpenClaw may exchange an attacker-obtained authorization code and persist tokens for the wrong Chutes account.
The automatic local callback flow is not affected (it validates state in the local HTTP callback handler).
Affected Packages / Versions
openclaw(npm):<= 2026.2.13when using the manual Chutes OAuth login flow.
Fix
The manual flow now requires the full redirect URL (must include code and state), validates the returned state against the expected value, and rejects code-only pastes.
