The Borderless – Addons and Templates plugin for Elementor suffers from a stored cross-site scripting vulnerability (CWE-79) due to improper neutralization of input in the 'title' parameter. Authenticated users with Contributor-level privileges or above can inject arbitrary JavaScript code that executes in the context of users viewing the compromised pages. This vulnerability affects all versions up to 1.7.1. The CVSS 3.1 base score is 6.4, reflecting network attack vector, low attack complexity, low privileges required, no user interaction, and impacts on confidentiality and integrity with no availability impact. No patch or vendor advisory is currently available, and no exploits have been observed in the wild.

Successful exploitation allows an authenticated user with Contributor or higher privileges to inject persistent malicious scripts into pages, which execute when other users view those pages. This can lead to unauthorized actions performed on behalf of users, theft of sensitive information, or session hijacking. The impact affects confidentiality and integrity but does not affect availability. Since the attacker must have authenticated access with at least Contributor privileges, the risk is limited to environments where such user roles exist.

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 removing or disabling the vulnerable plugin if possible. Monitor for plugin updates from visualmodo and apply them promptly once available. Avoid granting unnecessary Contributor or higher privileges to untrusted users.
