## Project history and usage

WuppieFuzz is TNO's open-source, coverage-guided REST API fuzzer built on LibAFL. The project targets black-box, grey-box, and white-box testing and emphasizes ease of use, explainable findings, and modularity.

### Project history

The project is developed under the TNO-S3 GitHub organization and is implemented primarily in Rust. Its README presents WuppieFuzz as a practical REST API fuzzing tool, while its academic publication frames it as coverage-guided, stateful REST API fuzzing driven by OpenAPI specifications and REST-specific mutators.

The tool's research context is modern API security. The TNO repository and 2025/2026 publication describe a workflow in which an OpenAPI specification seeds request sequences, LibAFL and REST-specific mutation explore behavior, and coverage measurements guide which request sequences are sent next to reach complex application states.

### Adoption history

WuppieFuzz has moved beyond a repository-only release into security tooling visibility: its README lists media coverage, a ONE Conference e-magazine feature, an OpenAPI.tools listing, a Nordic APIs talk, and a Thoughtworks Technology Radar mention. The preferred citation points to the ICISSP 2026 proceedings, giving it both an open-source and research footprint.

### How it is used

Users run WuppieFuzz against a target application and provide an OpenAPI specification so the fuzzer can generate and mutate requests. For coverage-guided setups, the README shows passing coverage configuration such as JaCoCo data for a Java target; the paper also describes harness automation and reports that help developers fix bugs.

### Why package nerds care

For security package collections, WuppieFuzz is notable because it brings LibAFL-style coverage-guided fuzzing into the REST API space instead of staying at the binary or library fuzzing layer. It sits near OpenAPI tooling, API security testing, Rust fuzzing infrastructure, and developer-friendly security automation.

### Timeline

- 2024: Project media coverage and conference visibility begin appearing in the upstream README.
- 2025: TNO's publication record lists WuppieFuzz as a conference paper.
- 2025-12-17: The WuppieFuzz paper is submitted to arXiv.
- 2026: The README identifies WuppieFuzz v1.6.0 and cites the ICISSP 2026 proceedings.

### Related projects

- WuppieFuzz is built on LibAFL and is comparable to other REST API fuzzers and API testing tools that consume OpenAPI specifications. The paper explicitly discusses black-box, grey-box, and white-box API fuzzing in relation to existing approaches such as EvoMaster.
