What is CVE-2025-6174?

The Qwizcards online quizzes and flashcards plugin for WordPress, versions up to 3.9.4, is vulnerable to a reflected cross-site scripting (XSS) flaw. The vulnerability arises because the plugin does not appropriately sanitize and escape the '_stylesheet' parameter before rendering it on the website. This lack of adequate input validation can allow attackers to craft malicious links, which if followed by users, especially those with higher privileges like administrators, could compromise their sessions and lead to unauthorized actions or data exposure.
