Add test cases for CLIXML deserialization vulnerability (CVE inspired by Truesec's research on attacking PowerShell CLIXML deserialization): - Test 18: Import-Clixml with untrusted -Path - Test 19: Import-Clixml with untrusted -LiteralPath - Test 20: ConvertFrom-CliXml with untrusted pipeline input - Test 21: Safe Import-Clixml with hardcoded path (no alert expected) Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> Copilot-Session: 5095179e-c63f-46d8-bf1b-27bd01de5f1d
…e deserialization sinks Add a new CliXmlDeserializationSink class that flags Import-Clixml and ConvertFrom-CliXml when untrusted data flows to their arguments. This covers both named/positional arguments and pipeline input. CLIXML deserialization can trigger .NET gadget chains leading to remote code execution, as demonstrated by Truesec's research on attacking PowerShell CLIXML deserialization.
