HighCVSS 8.8 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 36/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 1.8% (FIRST EPSS); higher than 79.2% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: ffmpeg (Debian:10) 7:4.1.8-0+deb10u1; ffmpeg (Debian:12) 7:4.3-2; ffmpeg (Debian:9) 7:3.2.15-0+deb9u3.

Low priority for now. Upgrade to ffmpeg (Debian:10) 7:4.1.8-0+deb10u1; ffmpeg (Debian:12) 7:4.3-2; ffmpeg (Debian:9) 7:3.2.15-0+deb9u3 or later.
