## Affected

- OpenClaw: fixed in 2026.2.14
- openclaw (npm): fixed in 2026.2.14

## Description

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.
