CVE-2024-2136 is a stored cross-site scripting vulnerability in the WPKoi Templates for Elementor WordPress plugin, specifically in the Advanced Heading widget. This vulnerability allows authenticated users with contributor-level access or above to inject arbitrary web scripts due to improper input sanitization and output escaping. The injected scripts execute when any user accesses the compromised page, potentially leading to session hijacking or other script-based attacks. The vulnerability affects all plugin versions up to and including 2.5.6. The CVSS 3.1 base score is 6.4, reflecting a medium severity with network attack vector, low attack complexity, and no user interaction required.

An attacker with contributor-level or higher privileges can inject malicious scripts into pages via the Advanced Heading widget. These scripts execute in the context of users who view the affected pages, potentially compromising user sessions or performing unauthorized actions within the victim's browser. The impact is limited to confidentiality and integrity loss; availability is not affected. There are no reports of known exploits in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict contributor-level access to trusted users only and consider disabling or limiting use of the Advanced Heading widget.
