Impact

A GCP Service Account Auth Key grants authentication credentials for a service account.

Exposure is a Critical Risk allowing an attacker to impersonate the service account and gain unauthorized access and management of cloud resources, leading to data breaches and financial impact.

How to Fix

To remediate exposed Auth tokens or Signing Keys:

1. Log in to your Identity Provider or OAuth provider settings.
2. Rotate the compromised Client Secret, Private Key, or Signing Certificate.
3. Update your application configuration with the new credentials.
4. Redeploy your application to ensure the new keys are in effect.

Next, remove the secret from your codebase:

1. Locate the exposed secret in your codebase.
2. Replace the hardcoded value with a secure variable or reference.

Finally, clean your version control history:

1. Permanently remove the sensitive data from your version control history to ensure it cannot be retrieved.

Warning: Rotating signing keys or client secrets will likely invalidate active user sessions or tokens. Be prepared for users to be logged out.
