CVE-2024-4664Public exploitNetwork attack vector

Stored XSS via unescaped floating-widget settings

Published Jun 27, 2024 · Updated Aug 1, 2024

Stored XSS in Ninja Team WP Chat App before 3.6.5 allows remote authenticated users to inject script through plugin settings. The floating-widget settings handler stores fields such as title and button label without adequate sanitization, then renders them without output escaping. Administrator-level access and another user's interaction with the affected interface are required for the stored script to execute in that user's browser, even when unfiltered_html is disabled.
