The Premium Addons for Elementor plugin for WordPress suffers from a stored cross-site scripting vulnerability (CWE-79) due to improper neutralization of input during web page generation. Specifically, the plugin fails to adequately sanitize and escape user-supplied attributes in its menu and shape widgets, allowing authenticated users with contributor-level privileges or higher to inject arbitrary JavaScript code. This code executes in the context of any user who views the compromised page, potentially leading to session hijacking or other client-side attacks. The vulnerability affects all versions up to and including 4.10.30. The CVSS 3.1 base score is 6.4, reflecting network attack vector, low attack complexity, and privileges required at the contributor level, with no user interaction needed and partial impact on confidentiality and integrity.

An attacker with contributor-level or higher access can inject persistent malicious scripts into pages via vulnerable widgets. These scripts execute in the browsers of users who visit the infected pages, potentially exposing sensitive information or enabling further attacks such as session hijacking. The vulnerability does not impact availability. No known exploits have been reported in the wild to date.

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 limiting use of the affected menu and shape widgets. Monitor for plugin updates from leap13 that address this vulnerability.
