What the vulnerability does
The FileBird – WordPress Media Library Folders & File Manager plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the folder name parameter in all versions up to, and including, 5.6.3 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with author access or higher, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
Explanation of Vulnerability in Simple Terms
FileBird versions up to 5.6.3 contain a stored cross-site scripting (XSS) vulnerability that allows authenticated users to inject malicious scripts into the media library. When other users interact with affected content, the injected code executes in their browser, potentially compromising their session or stealing sensitive data. The vulnerability affects the plugin's scope across WordPress, meaning it can impact multiple users and site functionality.
What an attacker can do
Inject malicious JavaScript that executes when other WordPress users view the media library.
Potential impact on your site
Other site users' sessions and data may be compromised when they access the media library; admin accounts are at higher risk.
Conditions required to exploit
Attacker must have a WordPress user account with at least low-level privileges (e.g., contributor or editor role).
