**Name of the Vulnerable Software and Affected Versions** phplist versions prior to 2.10.3 **Description** The issue is related to a cross-site scripting (XSS) vulnerability. This vulnerability allows remote attackers to inject arbitrary web script or HTML via the `unsubscribeemail` parameter in the index.php file. **Recommendations** For versions prior to 2.10.3, update to version 2.10.3 or later to resolve the issue. As a temporary workaround, consider restricting access to the index.php file or avoiding the use of the `unsubscribeemail` parameter until the update is applied.
