CVE-2024-3598 is a stored cross-site scripting vulnerability in the ElementsKit Pro WordPress plugin, specifically in the Creative Button widget. The issue is due to improper neutralization of input during web page generation, allowing authenticated users with contributor or higher privileges to inject arbitrary JavaScript code. This code executes in the context of any user viewing the injected page, potentially leading to information disclosure or session hijacking. The vulnerability affects all versions up to and including 3.6.0. 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 with no availability impact.

An attacker with contributor-level access or higher can inject persistent malicious scripts into pages via the Creative Button widget. These scripts execute in the browsers of users who visit the compromised pages, potentially leading to unauthorized disclosure of information or manipulation of page content. The vulnerability does not affect availability. There are no known active exploits in the wild, but the risk remains for sites using affected plugin versions without mitigation.

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 Creative Button widget if feasible. Monitor for updates from the vendor (wpmet) regarding patches or official mitigations.
