CVE-2023-28106Public exploitNetwork attack vector

Stored XSS via unsanitized URL-slug settings

Published Mar 16, 2023 · Updated Feb 25, 2025

Stored cross-site scripting in Pimcore before 10.5.19 allows remote attackers to execute JavaScript in another user's browser. DocumentControllerBase stores unescaped prettyUrl settings, while the page-settings UI accepts unsafe URL-slug characters without sanitization. Exploitation requires a crafted slug to reach an unsuspecting user, exposing data and allowing page actions in that user's session.
