Summary

FFmpeg through 9.0.2 is affected. Its libssh-based sftp protocol handler does not verify SSH host keys, which is a missing authentication step (CWE-322). A network attacker who performs man-in-the-middle, DNS, or ARP spoofing can impersonate an SFTP server and capture passwords supplied in sftp URLs, serve forged media, or receive uploaded output.
