The JetEngine plugin for WordPress suffers from a stored XSS vulnerability due to improper neutralization of input in the 'list_tag' parameter. This allows authenticated users with Contributor or higher privileges to inject arbitrary web scripts into pages. These scripts execute in the context of users who access the compromised pages, potentially leading to information disclosure or session hijacking. The vulnerability affects all versions up to and including 3.6.2. No patch or official fix information is currently available.

An attacker with Contributor-level or higher access can inject persistent malicious scripts via the 'list_tag' parameter. These scripts execute in the browsers of users who view the infected pages, potentially leading to limited confidentiality and integrity impacts such as theft of user data or unauthorized actions within the affected site. Availability is not impacted. The vulnerability requires authenticated access, reducing the attack surface.

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 affected 'list_tag' parameter if possible. Monitor vendor channels for updates and apply patches promptly once released.
