CVE-2025-27925Network attack vector

Authenticated data and service compromise via insecure deserialization

Published Mar 10, 2025 · Updated Mar 11, 2025

Insecure deserialization in Nintex Automation 5.6 through 5.7 allows remote authenticated users to compromise data and service operation. The vendor states that user input is deserialized without validation or sanitization but does not identify the affected component or serialization path. Network access and low-privileged authentication are required; successful exploitation can expose or alter data and interrupt service.
