libafl-wasm

A brief demo demonstrating libafl's compatibility with WASM, and how to do it.

In this example, the entire LibAFL harness and target are present in a WASM binary, which is then loaded by the example webpage. To run this example, do just build, then open the example webpage in your browser (via something like python3 -m http.server). The fuzzer will execute until finding a solution and will write the fuzzer log to your console.

In a real fuzzing campaign, you would likely need to also create a LibAFL Corpus implementation which was backed by JavaScript, and restart the fuzzing campaign by re-invoking the fuzzer and providing the associated corpora. This is not demonstrated in this barebones example.
