CVE-2026-33092

Local privilege escalation via environment variable handling

Published Apr 10, 2026 · Updated Apr 10, 2026

Local privilege escalation in Acronis True Image before build 42902 and its OEM edition before 42571 allows local users to gain elevated privileges. Acronis attributes the flaw to improper handling of environment variables but has not disclosed the affected component or unsafe operation. The local account must already hold low privileges; successful exploitation grants elevated control over protected data and system operations.
