The Plus Addons for Elementor plugin for WordPress contains a stored XSS vulnerability (CWE-79) due to improper neutralization of input in the 'menu_hover_click' parameter of the Navigation Menu Lite widget. This allows authenticated users with contributor or higher privileges to inject arbitrary scripts that execute in the context of other users viewing the injected pages. The vulnerability affects all versions up to 6.4.11. The CVSS 3.1 base score is 6.4, reflecting network attack vector, low attack complexity, low privileges required, no user interaction, and impacts on confidentiality and integrity with scope changed. No vendor patch or official remediation is currently documented.

Successful exploitation allows an authenticated contributor or higher to inject persistent malicious scripts into pages, which execute when other users access those pages. This can lead to partial confidentiality and integrity impact, such as session hijacking or unauthorized actions performed in the context of affected users. There is no impact on availability. No known active exploitation has been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict contributor-level access to trusted users only and consider disabling or limiting use of the Navigation Menu Lite widget if feasible. Monitor for updates from the vendor and apply patches promptly once available.
