Technical details
A Reflected Cross-Site Scripting (XSS) vulnerability exists in the stmcan RT-Theme 18 | Extensions (rt18-extensions) plugin for WordPress through version 2.5. The flaw stems from improper neutralization of user-supplied input during web page generation. An unauthenticated remote attacker can exploit this by tricking a user into clicking a malicious link or visiting a crafted URL. 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. As of the advisory date, no official patch has been released.
