        • cwe

        Because it is easy to extract strings from an application source code or binary, secrets should not be hard-coded. This is particularly true for applications that are distributed or that are open-source.

        In the past, it has led to the following vulnerabilities:

        • CVE-2022-25510
        • CVE-2021-42635

        Secrets should be stored outside of the source code in a configuration file or a management service for secrets.

        This rule detects variables/fields having a name matching a list of words (secret, token, credential, auth, api[_.-]?key) being assigned a pseudorandom hard-coded value. The pseudorandomness of the hard-coded value is based on its entropy and the probability to be human-readable. The randomness sensibility can be adjusted if needed. Lower values will detect less random values, raising potentially more false positives.

        Ask Yourself Whether

        • The secret allows access to a sensitive component like a database, a file storage, an API, or a service.
        • The secret is used in a production environment.
        • Application re-distribution is required before updating the secret.

        There would be a risk if you answered yes to any of those questions.

        Recommended Secure Coding Practices

        • Store the secret in a configuration file that is not pushed to the code repository.
        • Use your cloud provider’s service for managing secrets.
        • If a secret has been disclosed through the source code: revoke it and create a new one.

        Sensitive Code Example

        var secret = "47828a8dd77ee1eb9dde2d5e93cb221ce8c32b37" // Sensitive
        
        func main() {
            callMyService(secret)
        }
        

        Compliant Solution

        import "os"
        
        var secret = os.Getenv("SECRET")
        
        func main() {
            callMyService(secret)
        }
