Executive Summary

OpenClaw versions before 2026.8.1 have an authorization bypass vulnerability in the sessions.create endpoint. Attackers with write-scoped credentials can modify session configurations reserved for operator.admin scope, such as session model, provider, thinking level, and auth-profile settings. This allows them to redirect traffic and bypass administrative access controls.

Detection Guidance

Check OpenClaw versions before 2026.8.1 using commands like 'openclaw --version' or inspect package managers for outdated installations. Monitor logs for unauthorized modifications to session configurations via the sessions.create endpoint.

Impact Analysis

Attackers could redirect session traffic by altering configurations, potentially gaining unauthorized access to restricted resources. The impact is limited to models and credentials already configured by the operator, but it undermines administrative controls and could lead to data exposure or service disruption.

Compliance Impact

This vulnerability could lead to unauthorized access or data breaches, which may violate compliance requirements under GDPR, HIPAA, or other regulations. Bypassing administrative controls undermines data protection measures, potentially resulting in legal penalties or loss of trust.

Mitigation Strategies

Upgrade OpenClaw to version 2026.8.1 or later immediately. Avoid issuing write-only Gateway credentials to clients that can call keyed sessions.create before upgrading. Review and restrict access to session modification endpoints.
