Acronis True Image CVE-2026-33271

This vulnerability presents a moderate real-world risk constrained by multiple limiting factors. The CVSS score of 6.7 reflects a scenario with high impact (full confidentiality, integrity, availability compromise) but significant barriers to exploitation: local-only attack vector, high complexity, requirement for low-level authentication, and user interaction (UI:R). The EPSS exploitation probability and KEV status are not provided, preventing assessment of whether this is actively being exploited or has public proof-of-concept code. However, the combination of required user interaction and high complexity suggests this is not a critical vulnerability suitable for rapid automated exploitation at scale. Organizations running Acronis True Image in multi-user environments where untrusted users have local access face higher risk; single-user or enterprise-managed deployments face lower risk. The vulnerability should be prioritized for patching but does not constitute an emergency requiring out-of-band response.

An attacker with a standard user account on a Windows system running vulnerable Acronis True Image discovers that the application's installation directory has overly permissive folder permissions. The attacker navigates to or modifies a critical file within that directory (such as a configuration file or executable) and induces another user or triggers a scheduled task to execute the modified file, resulting in privilege escalation to the system or administrative level. While the attack requires local access and user interaction, organizations with shared or multi-user systems are at meaningful risk.
