The Elementor Website Builder Pro plugin for WordPress contains a stored cross-site scripting vulnerability (CWE-79) in versions up to 3.21.0. This flaw arises from improper neutralization of input during web page generation, allowing authenticated users with contributor-level permissions or higher to inject arbitrary web scripts into pages. These scripts execute in the context of users who view the affected pages, potentially leading to information disclosure or session hijacking. The vulnerability has a CVSS 3.1 base score of 6.4, reflecting network attack vector, low attack complexity, required privileges at the contributor level, no user interaction, and impacts on confidentiality and integrity with no availability impact. No patch or official fix has been documented in the provided data.

Successful exploitation allows authenticated contributors or higher to inject persistent malicious scripts into pages, which execute in the browsers of users who visit those pages. This can lead to unauthorized actions performed on behalf of users, theft of sensitive information, or other client-side impacts. The vulnerability affects confidentiality and integrity but does not impact 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 released, limit contributor-level permissions to trusted users only and consider additional input validation or security controls at the application or web server level to mitigate injection risks. Monitor official Elementor communications for updates on patches or mitigations.
