CVE-2026-33092: Privilege Escalation in Acronis True Image

Successful exploitation of CVE-2026-33092 could allow an attacker to escalate their privileges on a macOS system running vulnerable versions of Acronis True Image. This means a standard user could potentially gain administrative access, enabling them to install software, modify system settings, access sensitive data, and compromise the integrity of the entire system. The impact is particularly concerning in environments where user accounts have limited privileges, as this vulnerability provides a relatively straightforward path to gaining full control. While the specific attack vectors remain undisclosed, the improper handling of environment variables suggests potential manipulation of processes or services launched by Acronis True Image.

The primary mitigation for CVE-2026-33092 is to upgrade to Acronis True Image build 42902 or later. If immediate upgrading is not feasible due to compatibility issues or system downtime constraints, consider implementing stricter environment variable restrictions within the macOS system. This could involve limiting the scope of environment variables accessible to Acronis True Image processes or implementing runtime checks to validate environment variable values. While not a complete solution, this can reduce the attack surface. After upgrading, verify the fix by attempting to execute a process with elevated privileges and confirming that the environment variable manipulation fails.
