CVE-2023-2615Public exploitNetwork attack vector

Browser script execution via unencoded property name

Published May 10, 2023 · Updated Jan 27, 2025

Reflected XSS in Pimcore before 10.5.21 allows remote authenticated users to execute script in another user's browser via a property name. Predefined-property setters store user-controlled fields without HTML neutralization, and the deletion confirmation renders the decoded name. Exploitation requires low-privileged authentication and another user's interaction, enabling page modification, redirection, or session-cookie theft.
