Descriptions

The WordPress File Sharing Plugin WordPress plugin before 2.0.5 does not check authorization before displaying files and folders, allowing users to gain access to those filed by manipulating IDs which can easily be brute forced

El complemento WordPress File Sharing Plugin de WordPress anterior a 2.0.5 no verifica la autorización antes de mostrar archivos y carpetas, lo que permite a los usuarios obtener acceso a los archivados manipulando ID que pueden ser fácilmente forzados.

The WordPress File Sharing Plugin plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to 2.0.5 (exclusive) via the upvf_pro_preview_file function due to missing validation on a user controlled key. This makes it possible for unauthenticated attackers to gain access to files and folders belonging to other users.
