The Jeg Elementor Kit plugin for WordPress suffers from a stored cross-site scripting vulnerability (CWE-79) in its JKit - Banner widget. This vulnerability arises from improper neutralization of input during web page generation, allowing authenticated users with contributor or higher privileges to inject arbitrary JavaScript code. The injected scripts execute in the context of any user who views the compromised page, potentially leading to session hijacking or other client-side attacks. The issue affects all versions up to 2.6.4. The CVSS 3.1 base score is 6.4 (AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N), reflecting network attack vector, low attack complexity, required privileges, no user interaction, and partial impact on confidentiality and integrity with no impact on availability.

An attacker with contributor-level or higher access can inject persistent malicious scripts into pages via the vulnerable widget. These scripts execute in the browsers of users who visit the affected pages, potentially leading to theft of sensitive information or unauthorized actions performed on behalf of the user. The vulnerability impacts confidentiality and integrity but does not affect availability. There are no reports of active exploitation in the wild.

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