The Plus Addons for Elementor plugin for WordPress suffers from a stored cross-site scripting vulnerability (CWE-79) due to improper neutralization of input in the Progress Bar shortcode. This allows authenticated users with contributor-level access or above to inject arbitrary JavaScript code into pages, which executes in the context of users viewing those pages. The vulnerability affects all versions up to 6.4.9. The CVSS 3.1 base score is 6.4, reflecting network attack vector, low attack complexity, required privileges at the contributor level, no user interaction, and impacts on confidentiality and integrity but not availability. No vendor advisory or patch information is currently available, and the plugin is not a cloud service.

Successful exploitation allows an authenticated contributor or higher to inject persistent malicious scripts into pages via the Progress Bar shortcode. This can lead to unauthorized actions performed in the context of other users viewing the injected content, potentially compromising confidentiality and integrity of user data. There is no indication of impact to system 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, limit contributor-level access to trusted users only and consider disabling or restricting use of the Progress Bar shortcode. Monitor official vendor channels for updates and apply patches promptly once available.
