CVE-2026-28720· NVD / CVE Program· CNA Acronis

Unauthorized modification of settings due to insufficient authorization checks.

Noroxi assessment

Priority: Monitor (action score 17/100)

  • 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: 0.26% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Acronis Acronis Cyber Protect 17 41186.

Low priority for now. Upgrade to Acronis Acronis Cyber Protect 17 41186 or later.
