**Name of the Vulnerable Software and Affected Versions** Photos and Files Contest Gallery WordPress plugin versions prior to 21.3.1 **Description** The issue concerns a lack of sanitization and escaping of certain parameters, potentially allowing Cross-Site Scripting attacks by users with a role as low as author. **Recommendations** For versions prior to 21.3.1, update to version 21.3.1 or later to resolve the issue. As a temporary workaround, consider restricting the role of users to prevent potential exploitation until the update is applied. Avoid using vulnerable parameters in the plugin until the issue is resolved.
