WAF bypass techniques checklist: encoding bypass (URL/HTML/Unicode/double encoding), case variation, comment injection, HTTP header manipulation, chunked encoding, IP rotation, timing attacks, and payload obfuscation per WAF vendor. Use when WAF is blocking payloads during web app tests.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

# WAF Bypass Techniques

A Web Application Firewall (WAF) is a security tool that protects web applications from various attacks by analyzing HTTP requests and applying rules to identify and block suspicious traffic. This document outlines effective techniques to bypass WAF protections during security assessments.

How to install

The exact contents, by fingerprint
mdr add miosa-osa/osa/offensive-waf-bypass@sha256:927d9ca2fc3b9966

The line at the top of this page pins the label git:20260913.e13b6b8, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
