Seanime Argument Injection Vulnerability (CVE-2026-111728)

Short explanation

Seanime versions v3.7.0 to v3.10.3 contain an argument injection vulnerability due to improper authorization. Unauthenticated LAN or Tailnet clients can bypass security guards by injecting parameters into the ffmpeg argument vector, enabling file manipulation on the host.

Why does it matter?

This unauthenticated flaw allows attackers on the LAN or Tailnet to manipulate files on the host system and potentially read sensitive local data.

What should be done?

  • Monitor vendor advisories and updates
  • Review the provided commit patch
  • Restrict network access and untrusted client connections

Show the technical text from the sources

Seanime v3.7.0 to v3.10.3 contains an argument injection vulnerability reachable through improper authorization, allowing unauthenticated LAN or Tailnet clients to bypass the privileged mediastream settings guard by setting transcodeHwAccel to custom and supplying attacker-controlled decodeFlags and encodeFlags via the transcodeHwAccelCustomSettings field, which are appended verbatim to the ffmpeg argument vector. Attackers can trigger execution via the mediastream request and HLS playlist endpoints to achieve arbitrary file write and file truncation on the host as the user running seanime, with the injected input options also enabling potential arbitrary local file read and outbound data exfiltration through ffmpeg's protocol handlers.
