The LA-Studio Element Kit for Elementor plugin for WordPress suffers from a stored cross-site scripting vulnerability (CWE-79) in its Table of Contents widget due to improper neutralization of user-supplied input. Authenticated attackers with contributor or higher privileges can inject arbitrary JavaScript code that executes in the context of users visiting the compromised pages. This vulnerability affects all plugin versions up to 1.4.9. The CVSS 3.1 base score is 6.4, reflecting network attack vector, low attack complexity, low privileges required, no user interaction, and impacts on confidentiality and integrity with no availability impact. No known exploits in the wild have been reported, and no patch or official fix has been documented.

Successful exploitation allows an authenticated contributor or higher to inject and execute arbitrary scripts in the context of other users viewing the affected pages. This can lead to unauthorized disclosure of information and modification of content within the affected site. There is no direct impact on system availability. The vulnerability requires authenticated access with contributor-level privileges, limiting the attack surface to users with such access.

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 avoiding use of the Table of Contents widget in the LA-Studio Element Kit for Elementor plugin. Monitor for updates from the vendor for an official patch or mitigation.
