Attack Chain

1. An attacker gains access to a system with the vulnerable openclaw package installed.
2. The attacker crafts a malicious operator.write message intended to exploit the exposed Matrix profile persistence functionality.
3. The crafted message bypasses intended access controls due to the vulnerability.
4. The malicious message reaches the vulnerable Matrix profile persistence component.
5. The component processes the message without proper authorization checks.
6. The attacker modifies sensitive Matrix profile configurations, such as user permissions or system settings.
7. The modified configuration persists across system restarts due to the compromised persistence mechanism.
8. The attacker leverages the modified profile configuration to escalate privileges or gain unauthorized access to sensitive data.

Impact

Successful exploitation of this vulnerability could allow attackers to gain unauthorized control over Matrix profile configurations. This could lead to privilege escalation, unauthorized access to sensitive data, and potential disruption of service. While the exact scope of potential victims is unknown, any system running a vulnerable version of the openclaw package is at risk. This could impact various sectors relying on the package for their operations.

Recommendation

• Immediately upgrade the openclaw npm package to version 2026.4.10 or later to remediate the vulnerability.
• Monitor npm package installations and updates within your environment to detect and prevent the use of vulnerable versions of openclaw.
• Implement strict access controls and input validation on message-tool paths to prevent unauthorized access to sensitive functionalities.
