CVE-2023-45247

Protection-plan disclosure and manipulation via missing authorization

Published Oct 9, 2023 · Updated Jun 16, 2025

Missing authorization in Acronis Cyber Protect products before builds 36497 and 39169 allows local users to read and alter protection plans. Acronis has not published the affected component or the authorization check omitted when protection-plan data is accessed or changed. Low-privileged local access is required; successful exploitation exposes sensitive configuration and permits changes to antivirus and antimalware policy.
