Hello, I am a Premier CEP panel developer. 

I successfully used the session login method using an iframe in 2024 CEP11. 
Blocked in 2025 cep12.

iframe set-cookie test between 2024 Premier CEP 11 and 2025 Premier CEP 12
 
TEST: 
Server-generated cookie code:

<?php
setcookie('test_cookie', '1', 0, '/');
?>

Client Code: (index.html in panel)

<!doctype html>
<html>
<title>Basic Panel</title>
<head>	
</head>
<body> 
  <iframe src="http:/localhost:8000"/> 
</body>
</html>


2024 debug mode Check Cookies values:

2025 Debug Mode Cookies value:

Couldn't make it.

I am curious as to whether this setting is not applicable after upgrading from Chromium 88 to 99.

Is there a solution or is there anything else to check?

Your suspicion seems correct, that this isn't possible in Chromium 99 (part of CEP12).
