Description
The Contest Gallery plugin for WordPress contains a stored Cross-Site Scripting (XSS) flaw resulting from insufficient input sanitization and output escaping. This allows authenticated users with subscriber-level access or higher to inject arbitrary web scripts into pages, which then execute when other users visit the affected pages.
Recommendations
Update the plugin to a version later than 28.1.6.
