This vulnerability (CVE-2026-33092) involves improper handling of environment variables in Acronis True Image OEM and Acronis True Image for macOS, leading to local privilege escalation. The issue is classified under CWE-15 (Improper Neutralization of Special Elements in Output Used by a Downstream Component). It affects versions prior to build 42571 (OEM) and 42902 (standard) on macOS. The CVSS 3.0 vector indicates the attack requires local access with low complexity, no user interaction, and results in high impact on confidentiality, integrity, and availability.

An attacker with local access to a vulnerable macOS system running affected versions of Acronis True Image OEM can exploit this vulnerability to escalate privileges, potentially gaining higher-level access than intended. This could lead to full system compromise, including unauthorized access to sensitive data and disruption of system operations. No known exploits are reported in the wild, but the high CVSS score reflects significant potential impact.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict local access to trusted users only and monitor for suspicious activity related to Acronis True Image processes. Avoid running untrusted code on affected systems. Follow vendor communications closely for updates on patches or workarounds.
