The Elementor Website Builder 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 border, margin, and gap parameters are not properly sanitized or escaped, allowing authenticated users with Contributor-level permissions or above to inject malicious scripts. These scripts execute in the context of any user who views the affected pages, potentially leading to information disclosure or session hijacking. The vulnerability affects all versions up to 3.27.4. The CVSS 3.1 base score is 6.4, reflecting network attack vector, low attack complexity, privileges required, no user interaction, and impact on confidentiality and integrity but not availability.

An attacker with Contributor-level or higher access can inject persistent malicious scripts into pages via vulnerable parameters. This can lead to unauthorized script execution in the context of users viewing those pages, potentially compromising user data confidentiality and integrity. There is no impact on availability reported. The vulnerability does not require user interaction to trigger once the malicious content is injected.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, limit Contributor-level access to trusted users only and consider additional input validation or content filtering controls at the application or web server level. Monitor for updates from the Elementor plugin vendor and apply patches promptly once released.
