Warm up with SSRF URL filter repair diagnostic drill
Easy Security Basics arena: URL parsing, private network blocking, redirect handling, and allowlist policy
A learner is about to attempt the full SSRF URL filter repair arena. Build a smaller but realistic diagnostic that exposes whether they understand URL parsing, private network blocking, redirect handling, and allowlist policy. You are working inside a secure engineering review room, and the arena only clears when the result is safe, deterministic, and explainable.
Learn to apply URL parsing, private network blocking, redirect handling, and allowlist policy in a secure engineering review room while explaining the invariant, safety constraints, and hidden edge cases.
- Demonstrates URL parsing, private network blocking, redirect handling, and allowlist policy
- Handles the visible sample and hidden edge cases
- Keeps output deterministic and explainable
- Avoids unsafe dynamic execution
