The Jeg Kit for Elementor plugin for WordPress suffers from a stored cross-site scripting vulnerability due to improper neutralization of input in the 'sg_content_number_prefix' parameter. This allows authenticated users with contributor or higher privileges to inject arbitrary web scripts into pages. These scripts execute in the context of users who visit the compromised pages, potentially leading to information disclosure or session hijacking. The vulnerability affects all plugin versions up to 3.1.0. No vendor advisory or patch information is currently available, and the vulnerability has a CVSS 3.1 base score of 6.4 (medium severity).

An attacker with contributor-level or higher access can exploit this vulnerability to inject malicious scripts that execute in the browsers of users viewing the affected pages. This can lead to limited confidentiality and integrity impacts, such as theft of user session data or manipulation of page content. 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 removing or disabling the affected plugin if feasible. Monitor for updates from the vendor regarding patches or official mitigations.
