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: 2.3% (FIRST EPSS); higher than 83.6% of all records.
  • No special conditions are required; it is repeatable.
  • Fixed version: squid (Debian:12) 2.4.6-2.

Low priority for now. Upgrade to squid (Debian:12) 2.4.6-2 or later.
