Technical details

The BackWPup plugin for WordPress contains an unauthenticated Cross-Site Scripting (XSS) vulnerability in versions up to and including 5.7.4. The flaw stems from improper neutralization of user-supplied input during web page generation (CWE-79). A remote, unauthenticated attacker can exploit this by tricking a user into performing an action, such as clicking a malicious link. Successful exploitation allows the attacker to execute arbitrary JavaScript in the victim's browser session, which can lead to session hijacking or unauthorized actions on behalf of a privileged user. The issue is resolved in version 5.7.5.

Affected products

WP Media BackWPup <= 5.7.4
