CVE-2026-28477

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.

## 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.
