The Jeg Elementor Kit plugin for WordPress suffers from a stored cross-site scripting vulnerability (CWE-79) due to improper neutralization of input during web page generation. Specifically, the plugin fails to adequately sanitize and escape the custom attribute of links in multiple Elementor widgets. This allows authenticated attackers with contributor-level privileges or higher to inject arbitrary JavaScript code that executes in the context of users visiting the compromised pages. The vulnerability affects all versions up to 2.6.4 and has a CVSS 3.1 base score of 6.4, reflecting a medium severity. No patch or vendor advisory has been provided to date.

An attacker with contributor-level access or higher can inject malicious scripts into pages via the vulnerable plugin's custom link attributes. These scripts execute in the browsers of users who view the infected pages, potentially leading to session hijacking, defacement, or other client-side attacks. The vulnerability does not impact availability but can compromise confidentiality and integrity of user sessions and data within the affected WordPress site.

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 removing the Jeg Elementor Kit plugin if feasible. Monitor for updates from the vendor and apply any official patches promptly once available.
