The Elementor Website Builder plugin for WordPress suffers from a stored XSS vulnerability (CWE-79) in the 'url' parameter of its Icon widget. This occurs because input is not properly neutralized during web page generation, allowing authenticated users with Contributor or higher privileges to inject arbitrary JavaScript code. When other users access the compromised pages, the injected scripts execute, potentially leading to session hijacking or other client-side attacks. The vulnerability affects all versions up to and including 3.25.7. The CVSS 3.1 base score is 6.4, reflecting network attack vector, low attack complexity, privileges required, no user interaction, and impacts on confidentiality and integrity. No patch or vendor advisory is currently available, and no known exploits have been reported.

An attacker with Contributor-level or higher access can inject persistent malicious scripts into pages via the vulnerable 'url' parameter. These scripts execute in the context of users viewing the affected pages, potentially compromising user sessions or data confidentiality and integrity. The vulnerability does not impact availability. The medium CVSS score reflects moderate risk due to required privileges and the potential for client-side impact.

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 monitoring for suspicious activity related to page content modifications. Avoid granting unnecessary privileges that could be leveraged to exploit this vulnerability.
