Borderless Elementor Addons and Templates WordPress Plugin Stored Cross-Site Scripting Vulnerability

A stored cross-site scripting vulnerability has been identified in the Borderless - Elementor Addons and Templates plugin for WordPress, affecting all versions through 1.7.1. The vulnerability arises from inadequate input sanitization and output escaping, allowing authenticated attackers with Contributor-level access or higher to inject arbitrary scripts into pages. These scripts are executed when users access the compromised pages.

Impact

Exploitation of this vulnerability allows for stored cross-site scripting, where injected scripts are executed in the context of the user viewing the page.

Reproduction

To reproduce this vulnerability, an authenticated user with Contributor-level access can inject scripts through the 'title' parameter in any widget that supports this feature, such as the Circular Progress Bar, Progress Bar, or Semi-Circular Progress Bar widgets. The injected script will be executed when the page is viewed.

Remediation

Users are advised to update the Borderless - Elementor Addons and Templates plugin to version 1.7.2 or later, where this vulnerability has been fixed.
