The Pixel Gallery Addons for Elementor plugin for WordPress, including Easy Grid, Creative Gallery, Drag and Drop Grid, Custom Grid Layout, and Portfolio Gallery widgets, suffers from a stored cross-site scripting vulnerability (CWE-79). This occurs due to improper neutralization of input during web page generation, specifically insufficient sanitization and escaping of URLs. Authenticated attackers with Contributor-level privileges or higher can inject arbitrary JavaScript code that executes in the context of users viewing the compromised pages. The vulnerability affects all versions up to and including 1.6.7. The CVSS 3.1 score is 6.4 (AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N), reflecting network attack vector, low attack complexity, and partial confidentiality and integrity impact without availability impact. No vendor patch or advisory is currently provided.

Successful exploitation allows authenticated users with Contributor-level access or above to inject persistent malicious scripts into pages generated by the plugin's widgets. These scripts execute in the browsers of users who view the infected pages, potentially leading to theft of sensitive information, session hijacking, or other client-side attacks. The vulnerability impacts confidentiality and integrity but does not affect availability. There are no known active exploits reported.

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 plugin widgets. Monitor for plugin updates from bdthemes and apply them promptly once available.
