CVE-2023-1429Network attack vector

Session theft via unencoded document-type names

Published Mar 16, 2023 · Updated Feb 26, 2025

Reflected XSS in Pimcore before 10.5.19 allows remote authenticated users to execute script in another user's browser. The Document Types deletion handler passes the selected type's name to deleteConfirm without HTML encoding, so the dialog interprets crafted markup. The attacker needs Document Types permission and user interaction with deletion; executed script can read cookies or alter the displayed page.
