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. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
