Descriptions

The Photos and Files Contest Gallery WordPress plugin before 21.2.8.1 does not sanitise and escape some parameters, which could allow unauthenticated users to perform Cross-Site Scripting attacks via certain headers.

El complemento Photos and Files Contest Gallery de WordPress anterior a 21.2.8.1 no sanitiza ni escapa a algunos parámetros, lo que podría permitir a usuarios no autenticados realizar ataques de Cross-Site Scripting a través de ciertos encabezados.

The Photos and Files Contest Gallery – Contact Form, Upload Form, Social Share and Voting Plugin for WordPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via headers in all versions up to 21.2.8.1 (exclusive) due to insufficient input sanitization and output escaping.
