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 image box widget does not adequately sanitize or escape user input, allowing authenticated users with contributor or higher privileges to inject arbitrary JavaScript code. This code executes in the context of any user who views the compromised page, potentially leading to session hijacking or other script-based attacks. The vulnerability affects all versions up to and including 2.6.3. 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, scope change, and limited confidentiality and integrity impacts without availability impact.

An attacker with contributor-level or higher permissions can inject persistent malicious scripts into pages via the image box widget. These scripts execute in the browsers of users who visit the infected pages, potentially compromising user sessions or performing unauthorized actions within the context of the affected site. The vulnerability impacts confidentiality and integrity but does not affect availability. 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 permissions to trusted users only and consider disabling or limiting use of the image box widget. Monitor for plugin updates from jegtheme that address this vulnerability and apply them promptly once released.
