The Plus Addons for Elementor plugin for WordPress suffers from a stored cross-site scripting vulnerability (CWE-79) in its countdown widget. This vulnerability arises from improper neutralization of input during web page generation, allowing authenticated users with contributor or higher privileges to inject arbitrary JavaScript code. When other users access the compromised pages, the injected scripts execute in their browsers. The vulnerability affects all versions up to and including 5.4.2. The CVSS 3.1 base score is 6.4 (medium), with network attack vector, low attack complexity, privileges required at the contributor level, no user interaction needed, and impacts on confidentiality and integrity but not availability. No patch or official fix details are currently available.

An attacker with contributor or higher privileges can exploit this vulnerability to inject malicious scripts that execute in the context of other users viewing the affected pages. This can lead to unauthorized actions such as session hijacking or data theft limited to the confidentiality and integrity of user data accessible via the affected plugin. There is no impact on system availability. The vulnerability requires authenticated access and does not require user interaction to trigger the payload.

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 avoiding use of the countdown widget in The Plus Addons for Elementor plugin. Monitor for updates from the vendor and apply patches promptly once available.
