The Royal Elementor Addons and Templates for WordPress plugin suffers from a stored cross-site scripting vulnerability (CWE-79) due to improper neutralization of input in the 'inline_list' parameter. This allows authenticated users with contributor or higher privileges to inject arbitrary JavaScript code into pages. The injected scripts execute in the context of users who visit the compromised pages, potentially leading to session hijacking or other script-based attacks. The vulnerability affects versions up to 1.3.976. The CVSS 3.1 base score is 6.4, reflecting network attack vector, low attack complexity, required privileges at the contributor level, no user interaction, and impacts on confidentiality and integrity with no availability impact. No patch or official fix details are currently available.

An attacker with contributor-level access or higher can exploit this vulnerability to inject malicious scripts that execute in the browsers of users viewing the affected pages. This can lead to unauthorized actions such as theft of sensitive information or session tokens. The vulnerability impacts confidentiality and integrity but does not affect availability. There are no reports of active exploitation in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict contributor-level permissions to trusted users only and consider disabling or limiting use of the affected 'inline_list' parameter if possible. Monitor for updates from the vendor regarding patches or official mitigations.
