CriticalCVSS 9.6 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 38/100)

  • 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: 0.22% (FIRST EPSS).
  • 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: chromium (Debian:12) 149.0.7827.114-1~deb12u1; chromium (Debian:13) 149.0.7827.114-1~deb13u1; chromium (Debian:14) 149.0.7827.114-1.

Low priority for now. Upgrade to chromium (Debian:12) 149.0.7827.114-1~deb12u1; chromium (Debian:13) 149.0.7827.114-1~deb13u1; chromium (Debian:14) 149.0.7827.114-1 or later.
