CVE-2024-12328 is a stored cross-site scripting vulnerability in the MAS Elementor plugin for WordPress, affecting all versions up to and including 1.1.7. The issue occurs because the plugin does not properly sanitize or escape SVG file uploads, allowing authenticated users with Author-level access or higher to embed arbitrary scripts. These scripts execute in the context of any user who views the SVG file, potentially leading to session hijacking or other script-based attacks. The vulnerability has a CVSS 3.1 base score of 6.4, reflecting network attack vector, low attack complexity, required privileges at the Author level, no user interaction, and impacts on confidentiality and integrity with no availability impact.

An attacker with Author-level access can exploit this vulnerability to inject malicious scripts into SVG files uploaded to the site. These scripts execute in the browsers of users who view the SVG, potentially compromising user sessions or data confidentiality and integrity. The impact is limited to confidentiality and integrity with no direct availability impact. Since the attacker must have authenticated Author-level access, the risk is mitigated somewhat by the privilege requirement. No known exploits have been reported in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict Author-level access to trusted users only and consider disabling SVG file uploads if possible.
