**Name of the Vulnerable Software and Affected Versions** OpenRepeater versions prior to 2.2 **Description** The issue allows unauthenticated command injection via shell metacharacters in the `post service` parameter of the "functions/ajax system.php" API endpoint. **Recommendations** For versions prior to 2.2, update to version 2.2 or later to resolve the issue. As a temporary workaround, consider restricting access to the "functions/ajax system.php" API endpoint to prevent unauthenticated command injection. Avoid using the `post service` parameter in the affected API endpoint until the issue is resolved.
