**Name of the Vulnerable Software and Affected Versions** SourceCodester Complaint Management System version 1.0 **Description** A critical issue was found in the SourceCodester Complaint Management System. This issue affects the file /users/check availability.php of the component POST Parameter Handler. The manipulation of the `email` argument leads to sql injection. The attack can be initiated remotely. **Recommendations** For SourceCodester Complaint Management System version 1.0, consider restricting access to the /users/check availability.php file until a patch is available. As a temporary workaround, avoid using the `email` argument in the affected POST Parameter Handler to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this issue.
