LowCVSS 2.9 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 11/100)

  • 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: 0.14% (FIRST EPSS).
  • Someone with local access to the system can trigger it. No account or password is required. No user action is required. Special conditions such as timing or configuration are required.
  • Fixed version: uriparser (Debian:14) 1.0.1+dfsg-1; uriparser (openSUSE:Leap 15.6) 0.8.5-150000.3.11.1; uriparser (openSUSE:Leap 16.0) 0.9.8-160000.4.1.

Low priority for now. Upgrade to uriparser (Debian:14) 1.0.1+dfsg-1; uriparser (openSUSE:Leap 15.6) 0.8.5-150000.3.11.1; uriparser (openSUSE:Leap 16.0) 0.9.8-160000.4.1 or later.
