The ElementsKit Elementor Addons plugin for WordPress suffers from a stored cross-site scripting vulnerability (CWE-79) due to improper neutralization of input during web page generation. Authenticated attackers with Contributor or higher privileges can exploit insufficient sanitization of the URL attribute in a custom widget to inject arbitrary JavaScript. This malicious code executes in the context of users visiting the compromised page, potentially leading to session hijacking or other script-based attacks. The vulnerability affects all versions up to 3.5.2. No official patch or remediation information is provided in the available data.

An attacker with Contributor-level or higher access can inject persistent malicious scripts into pages via the URL attribute of a custom widget. These scripts execute in the browsers of users who visit the injected pages, potentially compromising user sessions or performing unauthorized actions within the context of the affected site. The vulnerability does not affect availability but impacts confidentiality and integrity. There are no known exploits in the wild at this time.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict Contributor-level access to trusted users only and consider disabling or removing the vulnerable plugin if possible. Monitor official roxnor or ElementsKit channels for updates and apply patches promptly once released.
