CVE-2026-107675
FFmpeg through 9.0.2 contains a missing host key verification vulnerability in the libssh-based sftp protocol handler that allows network attackers to impersonate SFTP servers.
Does this matter?
Lower severity and a low EPSS score (0.19%). Track it; it rarely justifies an emergency change on its own.
Description
FFmpeg through 9.0.2 contains a missing host key verification vulnerability in the libssh-based sftp protocol handler that allows network attackers to impersonate SFTP servers. Attackers performing man-in-the-middle, DNS, or ARP spoofing can capture passwords supplied in sftp URLs, serve forged media, or receive uploaded output.
