CVE-2023-2322Public exploitNetwork attack vector

Stored XSS via unencoded document link properties

Published Apr 27, 2023 · Updated Jan 31, 2025

Stored XSS in Pimcore before 10.5.21 allows remote authenticated users to run JavaScript in another administrator's browser. The document link editor builds fullpath by concatenating unencoded parameters and anchor values, allowing stored markup to enter rendered HTML. A user with document-editing access must store the payload, and another user must view the affected link for cookie theft, account impersonation, or redirection.
