Api Key Exposure on Heroku
How Api Key Exposure Manifests in Heroku
API key exposure in Heroku applications typically occurs through configuration mismanagement, logging practices, and deployment workflows. Heroku's platform-as-a-service model creates specific vulnerability patterns that developers must understand.
The most common exposure vector is environment variable leakage through logging. When Heroku dynos write logs, they capture stdout and stderr streams, which often include configuration dumps. Consider this problematic pattern:
Heroku-Specific Detection
Detecting API key exposure in Heroku requires both manual code review and automated scanning. The platform's architecture creates specific detection patterns that differ from traditional server deployments.
Manual detection starts with examining Heroku config vars. Use heroku config to list all environment variables, then search your codebase for references to these variables. Look for patterns like:
