CVE-2025-27358Network attack vector

Subscriber content injection via missing capability check

Published Jul 4, 2025 · Updated Apr 28, 2026

Missing authorization in N-Media Frontend File Manager 23.6 and earlier allows remote authenticated users to inject content into site pages. An undisclosed plugin function accepts subscriber-controlled content without performing the required capability check or neutralizing script-related HTML tags. Subscriber-level access and a privileged user's interaction are required; injected content can alter pages or present phishing content, with no reported data disclosure.
