Acronis DLP and Cyber Protect Agent Vulnerable to Privilege Escalation (CVE-2026-41952)
The National Vulnerability Database (NVD) has disclosed CVE-2026-41952, a critical vulnerability impacting Acronis DeviceLock DLP and Acronis Cyber Protect Cloud Agent on Windows. This flaw, stemming from improper input validation, allows for local privilege escalation. Attackers with initial low-level access can exploit this to gain administrative rights on affected systems. Versions prior to Acronis DeviceLock DLP build 9.0.93212 and Acronis Cyber Protect Cloud Agent build 42183 are confirmed to be vulnerable.
This vulnerability presents a significant risk to organizations relying on these Acronis products for data loss prevention and endpoint security. A successful exploit means an attacker can bypass security controls and potentially exfiltrate sensitive data or disrupt operations. Defenders must prioritize patching these systems to mitigate the immediate threat. The high CVSS score of 7.8 underscores the severity and exploitability of this issue.
What This Means For You
- If your organization uses Acronis DeviceLock DLP or Acronis Cyber Protect Cloud Agent, immediately verify your build versions. Patch to Acronis DeviceLock DLP build 9.0.93212 or Acronis Cyber Protect Cloud Agent build 42183 or later, and audit systems for any signs of unauthorized privilege escalation.
