Copilot Autofix

AI 3 months ago

To fix the issue, the sensitive data (password) should be securely handled before being included in the content parameter. Instead of transmitting the password directly, it should be encrypted or replaced with a secure token. Additionally, ensure that the HTTP request is sent over a secure channel (HTTPS). The fix involves modifying the code to obfuscate or encrypt the password before it is used in the content parameter.

Steps to implement the fix:

  1. Introduce encryption or tokenization for the password before it is included in the content parameter.
  2. Update the Utils.GetContainerRegistryAccessTokenFromSecretManagement method to return an encrypted or tokenized version of the password.
  3. Ensure that the receiving server can handle the encrypted/tokenized data appropriately.
