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: 1.1% (FIRST EPSS); higher than 67.2% 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: webkit2gtk3 (AlmaLinux:8) 2.46.3-1.el8_10; webkit2gtk3-devel (AlmaLinux:8) 2.46.3-1.el8_10; webkit2gtk3-jsc (AlmaLinux:8) 2.46.3-1.el8_10.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to webkit2gtk3 (AlmaLinux:8) 2.46.3-1.el8_10; webkit2gtk3-devel (AlmaLinux:8) 2.46.3-1.el8_10; webkit2gtk3-jsc (AlmaLinux:8) 2.46.3-1.el8_10 or later.
