Copilot Autofix

AI about 21 hours ago

To fix the issue, the sensitive data (password) should not be directly included in the content variable. Instead, the code should use a secure mechanism to transmit authentication information, such as an encrypted token or a secure header. If the password must be used, it should be hashed or encrypted before transmission. Additionally, the code should ensure that sensitive data is not logged or exposed in error messages.

The fix involves:

  1. Modifying the Utils.GetContainerRegistryAccessTokenFromSecretManagement method to return a secure token instead of a plaintext password.
  2. Updating the content variable in ContainerRegistryServerAPICalls.cs to use the secure token instead of the password.
  3. Ensuring that sensitive data is not logged or exposed in error messages.
