MediumCVSS 6.5 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 26/100)

  • 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: 0.54% (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: azl3 libsndfile 1.2.2-5 on Azure Linux 3.0 Release Notes; azl3 libsndfile 1.2.2-7 on Azure Linux 3.0 Release Notes; cbl2 libsndfile 1.0.31-4 on CBL-Mariner 2.0 Release Notes.

Low priority for now. Upgrade to azl3 libsndfile 1.2.2-5 on Azure Linux 3.0 Release Notes; azl3 libsndfile 1.2.2-7 on Azure Linux 3.0 Release Notes; cbl2 libsndfile 1.0.31-4 on CBL-Mariner 2.0 Release Notes or later.
