Noroxi assessment
Priority: Monitor (action score 32/100)
- 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: 5.1% (FIRST EPSS); higher than 92.5% of all records.
- Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
- Fixed version: libxcursor (Alpine:v3.10) 1.1.15-r0; libxcursor (Debian:12) 1:1.1.14-3.1; wayland (Debian:12) 1.14.0-2.
Low priority for now. Upgrade to libxcursor (Alpine:v3.10) 1.1.15-r0; libxcursor (Debian:12) 1:1.1.14-3.1; wayland (Debian:12) 1.14.0-2 or later.
