The Element Pack Addons for Elementor plugin for WordPress suffers from a stored cross-site scripting vulnerability (CWE-79) in multiple widgets including Dual Button, Creative Button, and Image Stack. This vulnerability arises from improper neutralization of input during web page generation, allowing authenticated users with Contributor-level permissions or higher to inject arbitrary web scripts. These scripts persist in the affected pages and execute in the context of any user viewing those pages. The issue affects all plugin versions up to and including 5.10.29. The CVSS 3.1 base score is 6.4, reflecting network attack vector, low attack complexity, privileges required, no user interaction, and impacts on confidentiality and integrity with scope changed.

An attacker with Contributor-level or higher privileges can exploit this vulnerability to inject malicious scripts that execute in the browsers of users who visit the infected pages. This can lead to unauthorized actions performed on behalf of users, data theft, or session hijacking. The impact is limited to confidentiality and integrity with no availability impact. Since the attacker must be authenticated with at least Contributor rights, the risk is mitigated somewhat by the need for such access.

No official patch or remediation is currently available for this vulnerability. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is released, restrict Contributor-level access to trusted users only and consider disabling or limiting use of the affected widgets to reduce exposure.
