The Element Pack Elementor Addons plugin for WordPress suffers from a stored cross-site scripting vulnerability due to improper neutralization of input in the custom_attributes field of widgets. Authenticated users with contributor or higher privileges can inject arbitrary JavaScript that executes in the context of any user viewing the affected page. This vulnerability exists in all versions up to and including 5.6.1. The CVSS 3.1 base score is 6.4 (medium severity), with network attack vector, low attack complexity, privileges required at the contributor level, no user interaction needed, and impacts confidentiality and integrity with no impact on availability. No official patch or remediation guidance is currently available from the vendor or other sources.

Successful exploitation allows an authenticated contributor or higher to inject persistent malicious scripts into pages, which execute in the browsers of users who view those pages. This can lead to unauthorized disclosure of information and modification of content within the affected site context. There is no indication of impact on system availability. No known active exploits have 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 the use of the affected plugin. Monitor vendor channels for updates and apply patches promptly once available.
