Noroxi assessment

Priority: Monitor (action score 21/100)

  • 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: 0.23% (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) 138.0.7204.49-1~deb12u1; chromium (Debian:13) 138.0.7204.49-1; chromium (openSUSE:Tumbleweed) 138.0.7204.96-1.1.

Low priority for now. Upgrade to chromium (Debian:12) 138.0.7204.49-1~deb12u1; chromium (Debian:13) 138.0.7204.49-1; chromium (openSUSE:Tumbleweed) 138.0.7204.96-1.1 or later.
