CVE-2023-44208

Sensitive data disclosure and modification via missing authorization

Published Oct 4, 2023 · Updated Apr 10, 2026

Missing authorization in Acronis Cyber Protect Home Office and Acronis True Image OEM allows local users to disclose and modify sensitive data. Acronis identifies no component, request path, or authorization decision that incorrectly permits the access, so the precise mechanism is undisclosed. Exposure requires local low-privileged access to Windows and affects Home Office before build 40713 and True Image OEM before build 42575.
