CVE-2025-3936 is a critical vulnerability affecting Tridium Niagara Framework and Enterprise Security on Windows, stemming from incorrect permission assignments for critical resources. This flaw allows attackers to exploit improperly configured access control security levels, impacting versions before 4.14.2, 4.15.1, and 4.10.11.
