## What is CVE-2026-80517?

CVE-2026-80517 is a low-severity cross-site scripting vulnerability in Unknown WP Ultimate CSV Importer, published on 3 Oct 2026. An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.

### Official 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.

Weakness: CWE-79 (Improper Neutralization of Input During Web Page Generation)
