Fuzzing RustPython with fusil
Author: devdanzinCreated Jul 19, 2026Updated Aug 14, 2026
Summary
Hello, I maintain and run a fuzzer called fusil. It is a fuzzer for Python that has been successfully used to find bugs in both the CPython and PyPy interpreters. In a PoC run, it seems able to fuzz RustPython.
I'd like to know whether you'd be interested in a fuzzing campaign targeting RustPython, so I don't spend time and energy on it if it's not a good fit for you.
