The Essential Addons for Elementor plugin for WordPress suffers from a stored XSS vulnerability due to improper neutralization of input during web page generation. Specifically, URL attributes in widgets do not undergo adequate sanitization or output escaping, enabling authenticated attackers with contributor or higher privileges to inject arbitrary JavaScript code. This code executes in the context of users visiting the affected pages, potentially leading to session hijacking or other client-side attacks. The vulnerability affects all versions up to and including 5.9.14 and is tracked as CVE-2024-3333 with a CVSS 3.1 base score of 6.4.

An attacker with contributor-level or higher access can inject persistent malicious scripts into pages via widget URL attributes. These scripts execute in the browsers of users who view the infected pages, potentially compromising user sessions or performing unauthorized actions within the context of the affected site. The vulnerability does not impact availability but affects confidentiality and integrity to a limited extent as indicated by the CVSS vector (C:L/I:L/A:N). 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 disabling or limiting the use of the affected plugin.
