The Royal Elementor Addons and Templates plugin for WordPress suffers from a stored cross-site scripting vulnerability via the '_elementor_data' parameter. This flaw arises from improper neutralization of input during web page generation, allowing authenticated attackers with Contributor-level privileges or higher to inject malicious scripts into pages. These scripts execute in the context of users viewing the compromised pages, potentially leading to information disclosure or session hijacking. The vulnerability affects all versions up to and including 1.7.1020. There is no vendor advisory or patch information provided at this time.

An attacker with Contributor-level or higher access can exploit this vulnerability to inject persistent malicious scripts into pages managed by the plugin. These scripts execute in the browsers of users who view the infected pages, potentially leading to theft of sensitive information, session tokens, or other client-side impacts. The vulnerability does not affect availability and requires authenticated access, limiting the attack surface. No known exploits in the wild have been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict Contributor-level access to trusted users only and consider disabling or replacing the affected plugin to prevent exploitation.
