WP Ultimate CSV Importer lets admins inject scripts

CVE-2026-80517 · published 16 days ago
Summary

The WP Ultimate CSV Importer plugin for WordPress, versions before 9.2, lets administrators upload files that can contain hidden code. That code is saved to a publicly reachable location and can run in the browsers of anyone who opens the file, even higher‑level users. Update the plugin to version 9.2 or later, or stop using it, to stop this risk.

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.
