CVE-2022-40373Public exploitNetwork attack vector

Authenticated script execution via crafted XML upload

Published Dec 15, 2022 · Updated Apr 21, 2025

Cross-site scripting in FeehiCMS 2.1.1 allows remote authenticated users to execute JavaScript by uploading a crafted XML file. The public report identifies the backend XML upload path but does not disclose the handler or the exact output context that omits neutralization. Low-privileged access and a victim opening the affected content are required; resulting script execution can read or alter browser-accessible data.
