The Plus Addons for Elementor plugin for WordPress suffers from a stored XSS vulnerability (CWE-79) in the carousel_direction parameter of its testimonials widget. Authenticated users with contributor or higher privileges can inject arbitrary scripts due to improper input sanitization and output escaping. This vulnerability affects all versions up to and including 5.6.2. The CVSS 3.1 base score is 6.4 (medium severity), with network attack vector, low attack complexity, privileges required, no user interaction, and impacts confidentiality and integrity. No patch or vendor advisory is provided, and no known exploits exist currently.

An attacker with contributor-level or higher access can inject malicious scripts that execute in the context of users visiting the compromised pages. This can lead to unauthorized actions or data disclosure limited to the scope of the affected site. The vulnerability impacts confidentiality and integrity but does not affect availability. Since it requires authenticated access, the risk is somewhat mitigated by the need for contributor privileges.

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 testimonials widget with the carousel_direction parameter. Monitor for updates from the vendor posimyththemes regarding patches or official mitigations.
