MediumCVSS 6.1 · v3.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 25/100)

  • 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: 1.7% (FIRST EPSS); higher than 78.2% 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: wordpress (Debian:12) 4.7.1+dfsg-1; wordpress (Debian:7) 3.6.1+dfsg-1~deb7u13; wordpress (Debian:8) 4.1+dfsg-1+deb8u12.

Low priority for now. Upgrade to wordpress (Debian:12) 4.7.1+dfsg-1; wordpress (Debian:7) 3.6.1+dfsg-1~deb7u13; wordpress (Debian:8) 4.1+dfsg-1+deb8u12 or later.
