Alert meAnalysisAIv1 – Mar 12, 2026
OpenClaw versions before 2026.2.14 fail to properly validate OAuth state parameters in the Chutes login flow, allowing attackers to bypass CSRF protections and hijack user sessions. An attacker can trick a user into pasting malicious OAuth callback data to gain unauthorized access and maintain persistent tokens under a compromised account. No patch is currently available for this high-severity vulnerability.

Lifecycle Timeline
2DescriptionCVE.org
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.
Executive ViewAI
OpenClaw instances using the Chutes login flow are vulnerable to CSRF attacks due to improper OAuth state validation, potentially allowing attackers to hijack user sessions and gain unauthorized access to organizational accounts. This affects any user relying on manual Chutes authentication and requires immediate mitigation since no patch is currently available.
Disable the manual Chutes login flow if operationally feasible; implement WAF rules to detect and block suspicious state parameter manipulation; enforce multi-factor authentication for all OpenClaw users; restrict Chutes login access to trusted networks only; implement additional CSRF token validation at application layer if possible; monitor session activity for anomalous login patterns.
