Technical details

The WPAdverts plugin for WordPress is vulnerable to Unauthenticated Reflected Cross-Site Scripting (XSS) in versions up to 2.3.1 due to improper neutralization of user-supplied input (CWE-79). An unauthenticated remote attacker can exploit this by tricking a user into clicking a malicious link or visiting a crafted page. Successful exploitation allows the execution of arbitrary JavaScript in the context of the victim's browser session, which can lead to session hijacking or unauthorized actions. The vulnerability is addressed in version 2.3.2.
