In the "/EPMUI/ModalDlgHandler.ashx?value=showReadonlyDlg" endpoint, it is possible to inject code in the "modalDlgMsgInternal" parameter via POST, which is then executed in the browser. The risk of exploiting vulnerability is reduced due to the required additional bypassing the Content-Security-Policy policy

This issue affects CyberArk Endpoint Privilege Manager in SaaS version 24.7.1. The status of other versions is unknown. After multiple attempts to contact the vendor we did not receive any answer.
