Does this matter?

Lower severity and a low EPSS score (0.13%). Track it; it rarely justifies an emergency change on its own.

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.
