A Server-Side Request Forgery (SSRF) occurs when an application takes a user-supplied URL (for example, to upload a profile picture from a link or generate a PDF from a webpage) and fails to validate it.
If the application's file-fetching mechanism accepts the file:/// protocol handler, it acts as an arbitrary file read vulnerability. The application reads files directly from the local server's file system and prints the contents back to the attacker's HTTP response.

Minimize the fallout of a potential compromise by ensuring your application secrets are not stored permanently or in plaintext within environment variables. Consider using dedicated secrets management architectures like HashiCorp Vault or AWS Secrets Manager, which fetch tokens dynamically and inject them securely via memory rather than global process environments.
