OpenClaw versions prior to 2026.2.14 contain an oauth state validation bypass vulnerability in the manual Chutes login flow that allows attackers to bypass CSRF protection. An attacker can convince a user to paste attacker-controlled OAuth callback data, enabling credential substitution and token persistence for unauthorized accounts.

Ein Angreifer kann diese Schwachstellen in OpenClaw ausnutzen, um beliebigen Programmcode auszuführen, sich erhöhte Berechtigungen zu verschaffen, Sicherheitsmaßnahmen zu umgehen, Daten zu manipulieren, einen Denial-of-Service-Zustand herbeizuführen, vertrauliche Informationen offenzulegen oder andere, nicht näher bezeichnete Angriffe durchzuführen.
- GHSA-7rcp-mxpq-72pjOpenClaw Chutes manual OAuth state validation bypass can cause credential substitution2026-02-18ghsa · osvUS
## 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): `<= 2026.2.13` when 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. ## Fix Commit(s) - a99ad11a4107ba8eac58f54a3c1a8a0cf5686f47 Thanks @aether-ai-agent for reporting.
