CVE-2026-28493: ImageMagick has a Integer Overflow leading to out of bounds write in SIXEL decoder

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: 0.22% (FIRST EPSS).
  • Anyone who can reach it over the internet 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: ImageMagick ImageMagick 7.1.2-16.

Low priority for now. Upgrade to ImageMagick ImageMagick 7.1.2-16 or later.
