  "description": "\u003Cp\u003EA security feature bypass vulnerability exists in Windows Defender Application Control (WDAC) which could allow an attacker to bypass WDAC enforcement. An attacker who successfully exploited this vulnerability could circumvent Windows PowerShell Constrained Language Mode on the machine.\u003C/p\u003E\n\u003Cp\u003ETo exploit the vulnerability, an attacker would first have to access the local machine, and then place PowerShell into Constrained Language mode. By doing that an attacker could leverage script debugging to abuse signed modules in an unintended way.\u003C/p\u003E\n\u003Cp\u003EThe update addresses the vulnerability by correcting how PowerShell functions in Constrained Language Mode.\u003C/p\u003E",
