CVE-2022-23599Network attack vector

Cache-poisoned XSS and redirect via unvalidated Referer

Published Jan 28, 2022 · Updated May 5, 2025

Reflected XSS and open redirect in Products.ATContentTypes before 3.0.6 allow remote attackers to poison cached image pages. The image_view_fullscreen.pt template copied the request's unvalidated HTTP Referer into its back-link, allowing an attacker-controlled URL to persist in a shared cache. When caching includes that page, a later visitor who clicks the poisoned link is redirected or executes script in the page's origin; exposure usually concerns anonymous visitors.
