CVE-2026-0705

Local privilege escalation via insecure folder permissions

Published Jan 27, 2026 · Updated Jan 27, 2026

Incorrect default permissions in Acronis Cloud Manager before 6.4.25342.354 allow local users to elevate privileges on Windows. Acronis identifies insecure permissions on a folder but has not disclosed the folder, affected component, or privileged operation that consumes its contents. Exploitation requires low-privileged local access, high complexity, and user interaction, and grants control equivalent to the privileged operation.
