Server-Side Request Forgery (SSRF)

Summary of the Provided Code

The provided code is a set of test cases designed to validate the security measures implemented in an application against Server-Side Request Forgery (SSRF) attacks. The tests are written in various programming languages and frameworks, including Python with pytest, JavaScript with Jest, TypeScript using Playwright API testing, and a sample implementation in Java.

Key Components

1. Test Cases:

   • Ensure that the application rejects requests to cloud metadata endpoints.
   • Verify that localhost variants (e.g., http://localhost/) are blocked.
   • Confirm that non-standard representations of IP addresses (as per CVE-2024-29415) do not bypass security measures.
   • Validate that internal network ranges (private IPs) are rejected.
   • Ensure that external URLs remain accessible.

2. Metadata Markers:

   • The test cases check for specific markers in the response content to ensure that sensitive metadata is not leaked.

3. Logging and Assertions:

   • Each language-specific implementation includes logging statements and assertions to validate the expected behavior of the application under test.
