Excessive Use of Hard-Coded Literals in Initialization

Hard-coding values like database connection strings, API endpoints, cryptographic salts, or directory paths makes code rigid and difficult to update. When these values need to change—for instance, during deployment to a new environment or in response to a security incident—developers must search through and modify the source code directly, which is error-prone and time-consuming. This practice violates the principle of separating configuration from code. From a security perspective, this rigidity slows down vulnerability remediation and increases the chance of mistakes. If a hard-coded credential or insecure URL needs to be fixed, the change requires a full code modification and redeployment, rather than a simple configuration update. This delay can extend the window of exposure. Furthermore, the scattered, opaque nature of hard-coded values makes security reviews and audits more difficult, potentially allowing vulnerabilities to go unnoticed.
