CSE seems to not handle some special characters such as # < > when passed as values in commandToExecute

I have a CSE as part of a Bicep template that is passing a password secret value through protectedSettings -> commandToExecute like such -

properties: { publisher: 'Microsoft.Compute' type: 'CustomScriptExtension' typeHandlerVersion: '1.10' autoUpgradeMinorVersion: true settings: { fileUris: [ uri(templateBaseUrl, 'artifacts/Bootstrap.ps1') ] commandToExecute: 'powershell.exe -ExecutionPolicy Bypass -File Bootstrap.ps1 -adminUsername ${windowsAdminUsername} -adminPassword ${windowsAdminPassword}

If windowsAdminPassword contains one of # < > then CSE seems to not handle this and truncates the value.

Checking status.0 on a test machine I can see that it correctly holds the value with the special character.

[{"version":"1","timestampUTC":"2023-01-23T21:32:23.1378235Z","status":{"name":"powershell.exe -ExecutionPolicy Bypass -File Bootstrap.ps1 -adminUsername arcdemo -adminPassword vk3jyL!24dCTA1>jYrkor9}]

But when I look at the actual PowerShell script execution I can see the value was truncated when the script is run.

Is there a better way in CSE to handle these characters or is this a known issue/limitation?

I should have submitted this on CSE for Windows. Apologies

Is there a diff repo for CSE Windows issues? I cant seem to find it.
