## Technical details

A reflected Cross-Site Scripting (XSS) vulnerability exists in the Media Library Assistant plugin for WordPress due to improper neutralization of user-supplied input during web page generation (CWE-79). The vulnerability can be exploited by an unauthenticated attacker who crafts a malicious URL and convinces a privileged user to click it. Because the application fails to properly sanitize input before rendering it back to the browser, the attacker's script executes within the context of the victim's session. This can result in session hijacking, cookie theft, or unauthorized administrative actions. The issue is resolved in version 3.36.
