Category	Sensitive Tokens
Severity	MEDIUM
Framework	Git

Impact

A CircleCI Personal Token grants full read and write permissions for API interaction with CI/CD services.

Exposure of this token allows an attacker to execute unauthorized workflows, manipulate build processes, or access sensitive environment variables, leading to supply chain disruption or data exfiltration.

How to Fix

To remediate exposed Source Control or CI/CD tokens:

1. Log in to the relevant system or provider.
2. Navigate to the settings menu to locate the exposed credential.
3. Revoke or delete the compromised token immediately.
4. Generate a new token if continued access is required.
5. Update any dependent systems or services with the new credential.

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.
