The Royal Elementor Addons and Templates plugin for WordPress suffers from a stored cross-site scripting vulnerability (CWE-79) in its Woo Grid widget. This vulnerability allows authenticated users with Contributor-level privileges or higher to inject malicious scripts into pages. The root cause is insufficient sanitization and escaping of user input during page generation. When other users access these pages, the injected scripts execute in their browsers, potentially leading to session hijacking or other script-based attacks. The vulnerability affects all versions up to 1.7.1012. The CVSS 3.1 score of 6.4 reflects a medium impact with network attack vector, low attack complexity, and no user interaction required.

An attacker with Contributor-level access or higher can inject persistent malicious scripts into pages via the Woo Grid widget. These scripts execute in the context of users viewing the compromised pages, potentially leading to information disclosure or session hijacking. The vulnerability does not impact availability and requires authenticated access, limiting the attack surface. 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 Woo Grid widget. Monitor for plugin updates from wproyal and apply them promptly once available.
