A privilege escalation vulnerability in OpenClaw allows authenticated operators to modify administrative settings and persistence mechanisms, posing a significant risk to system integrity.

This is an improper privilege management flaw (CWE-269) where the application fails to perform adequate access control checks on the send endpoint. An authenticated user with operator.write privileges can bypass intended restrictions to access and modify restricted administrative Telegram configurations and cron persistence settings.

The ability for a lower-privileged operator to manipulate administrative configurations and persistence tasks represents a critical threat to the confidentiality and integrity of the application environment. Successful exploitation could lead to unauthorized system control or the establishment of persistent backdoors, directly impacting the availability and security posture of the infrastructure. Given the CVSS score of 7.1, this vulnerability is categorized as High severity, necessitating prompt remediation to prevent unauthorized administrative actions.

Immediate Action: Update the OpenClaw package to version 2026.3.28 or later to incorporate the necessary access control checks.

Proactive Monitoring: Review system and application audit logs for unauthorized access to the send endpoint or suspicious modifications to cron jobs and Telegram configuration files.

Compensating Controls: Implement strict network segmentation and restrict access to the application interface to trusted internal networks to limit the potential pool of attackers who could leverage compromised operator credentials.

Public Exploit Available: Unknown.

Organizations utilizing OpenClaw must prioritize updating to version 2026.3.28 immediately to address this privilege escalation flaw. Failure to patch allows authenticated operators to overstep their defined roles, potentially compromising the entire administrative backend. Please audit current operator accounts for suspicious activity as part of the remediation verification process.
