The Plus Addons for Elementor Stored Cross-Site Scripting Vulnerability

A stored cross-site scripting vulnerability has been identified in The Plus Addons for Elementor WordPress plugin, specifically in versions through 6.2.2. This vulnerability allows authenticated attackers with Contributor-level access and above to inject arbitrary web scripts into pages via the Countdown, Syntax Highlighter, and Page Scroll widgets. The injected scripts are executed when users access the affected pages, exploiting insufficient input sanitization and output escaping.

Impact

Reproduction

To reproduce this vulnerability, an authenticated user with Contributor-level access or higher can inject scripts into pages using the Countdown, Syntax Highlighter, or Page Scroll widgets. The injected scripts will then be executed when the page is viewed by any user.

Remediation

Users are advised to update the plugin to version 6.2.3 or a newer patched version.
