## What it is
FastJsonParty is a collection of Dockerized vulnerable environments covering multiple FastJson versions (1.2.47, 1.2.68, 1.2.80) for practicing black-box exploitation of JNDI injection, deserialization, file read/write, and WAF bypass techniques. Each scenario is launched via docker compose and includes hidden flag files to capture, with accompanying PoC write-ups.

## Use cases
- practice exploiting fast jndi injection vulnerabilities
- learn fast deserialization attacks in a safe lab
- train on waf bypass techniques for fast
- practice file write rce via fast 1.2.68
- simulate no-outbound-network exploitation scenarios
- set up a ctf-style flag hunting environment for java deserialization
- study fast 1.2.80 bypass chains

## When to choose
- you want hands-on practice with fast vulnerabilities across versions
- you need ready-made docker environments for security training or ctf practice
- you are studying jndi injection and deserialization exploitation from a black-box perspective

## When to avoid
- you need a production-safe JSON library rather than a vulnerable target
- you cannot run docker containers locally
- you want automated vulnerability scanning rather than manual exploitation practice

## Facets
- artifact type: application
- maturity: active
- function: security, penetration-testing, vulnerability-scanning, developer-tools
- domain: security, penetration-testing, developer-tools, self-hosted
- platform: self-hosted
- tags: fast, jndi-injection, deserialization, vulnerable-lab, ctf, docker-compose, exploitation-practice, waf-bypass, docker, linux
