CVE-2024-13734 is a stored cross-site scripting vulnerability (CWE-79) in the Card Elements for Elementor plugin for WordPress, specifically in the Profile Card widget. The issue stems from improper neutralization of input during web page generation, where user-supplied attributes are not adequately sanitized or escaped. Authenticated attackers with contributor-level privileges or higher can exploit this to inject arbitrary JavaScript that executes in the context of users viewing the compromised pages. The vulnerability affects all versions up to and including 1.2.6. The CVSS 3.1 base score is 6.4, reflecting network attack vector, low attack complexity, required privileges, no user interaction, and partial confidentiality and integrity impact without availability impact.

An attacker with contributor-level or higher access can inject persistent malicious scripts into pages via the Profile Card widget. These scripts execute in the browsers of users who view the infected pages, potentially leading to session hijacking, defacement, or other client-side attacks. The impact is limited to confidentiality and integrity of user data and interactions within the affected WordPress site. There is no indication of availability impact or exploitation 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, restrict contributor-level access to trusted users only and consider disabling or removing the Profile Card widget to mitigate risk. Monitor for updates from the plugin vendor or WordPress security channels for an official patch or temporary workaround.
