MediumCVSS 6.1 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 24/100)

  • 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% (FIRST EPSS); higher than 65.4% 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: github.com/caddyserver/caddy (Go) 2.5.0; github.com/caddyserver/caddy/v2 (Go) 2.5.0; caddy (openSUSE:Leap 15.4) 2.5.1-bp154.2.5.1.

Low priority for now. Upgrade to github.com/caddyserver/caddy (Go) 2.5.0; github.com/caddyserver/caddy/v2 (Go) 2.5.0; caddy (openSUSE:Leap 15.4) 2.5.1-bp154.2.5.1 or later.
