CyberRota Analysis
AI-GeneratedThe WP Ultimate CSV Importer plugin for WordPress versions prior to 9.2 is vulnerable due to inadequate validation of file types and lack of content sanitization for uploaded archives, which can lead to Stored Cross-Site Scripting (XSS) attacks. This vulnerability allows high privilege users, including site administrators, to execute malicious scripts in the sessions of users accessing the affected files, posing a significant risk, especially on Multisite installations. WordPress site administrators and security teams should prioritize updating to version 9.2 or later to mitigate this risk.
Original NVD Description
The WP Ultimate CSV Importer WordPress plugin before 9.2 does not properly validate the file types contained in an uploaded archive nor sanitise their content before storing them in a publicly served location, allowing high privilege users such as administrators to achieve Stored Cross-Site Scripting. On Multisite installations a site Administrator does not hold the unfiltered_html capability, so this lets them run scripts in the session of users who view the file, including Network Super Admins.
