Sensitive Information Disclosure In Source Code

This occurs when sensitive data such as passwords, API keys, or encryption secrets are hardcoded or accidentally exposed in the application’s source code or configuration files. Such data can easily be accessed and misused by attackers.

To mitigate this risk, sensitive information should never be hardcoded and must instead be stored securely using environment variables or secret management tools. Regular code reviews and automated scans can help detect accidental exposures before attackers exploit them.

Attack

  • Attackers search public or poorly secured repositories for exposed secrets.
  • Using automated tools, they scan codebases and version histories to extract credentials, API tokens, or encryption keys gaining unauthorized access to databases or services.
Impact

  • Unauthorized access to databases, APIs, or internal systems.
  • Data breaches and service misuse.
  • Credential leaks even from old code commits.
Solution

  • Revoke and rotate exposed keys or credentials immediately.
  • Remove secrets from code and commit history (use tools like BFG Repo-Cleaner).
  • Store secrets securely in environment variables or vaults.
  • Restrict repository access and enable MFA for developers.
