- Use std::sync::LazyLock to construct Sanitizer, Validator, and LeakDetector once instead of on every fuzz iteration (they compile regex/Aho-Corasick) - Remove fuzz_config_env assertion that panics on null-byte-only input - Remove no-op length check with misleading comment in fuzz_config_env - Update fuzz_config_env description in README to match actual behavior Co-Authored-By: Claude Opus 4.6 <[email protected]>

# IronClaw Fuzz Targets
|
|
|
|
Fuzz testing for security-critical input parsing paths using [cargo-fuzz](https://github.com/rust-fuzz/cargo-fuzz) (libFuzzer).
|
|
|
|
## Targets
|
|
|
|
| Target | What it exercises |
|
|
|--------|-------------------|
|
|
| `fuzz_safety_sanitizer` | Prompt injection pattern detection (Aho-Corasick + regex) |
|
|
| `fuzz_safety_validator` | Input validation (length, encoding, forbidden patterns) |
|
|
| `fuzz_leak_detector` | Secret leak detection (API keys, tokens, credentials) |
|
|
| `fuzz_tool_params` | Tool parameter and schema JSON validation |
|
|
| `fuzz_config_env` | Combined safety primitives (sanitize, validate, leak detect) |
|
|
|
|
## Setup
|
|
|
|
```bash
|
|
cargo install cargo-fuzz
|
|
rustup install nightly
|
|
```
|
|
|
|
## Running
|
|
|
|
```bash
|
|
# Run a specific target (runs until stopped or crash found)
|
|
cargo +nightly fuzz run fuzz_safety_sanitizer
|
|
|
|
# Run with a time limit (5 minutes)
|
|
cargo +nightly fuzz run fuzz_leak_detector -- -max_total_time=300
|
|
|
|
# Run all targets for 60 seconds each
|
|
for target in fuzz_safety_sanitizer fuzz_safety_validator fuzz_leak_detector fuzz_tool_params fuzz_config_env; do
|
|
echo "==> $target"
|
|
cargo +nightly fuzz run "$target" -- -max_total_time=60
|
|
done
|
|
```
|
|
|
|
## Adding New Targets
|
|
|
|
1. Create `fuzz/fuzz_targets/fuzz_<name>.rs` following the existing pattern
|
|
2. Add a `[[bin]]` entry in `fuzz/Cargo.toml`
|
|
3. Create `fuzz/corpus/fuzz_<name>/` for seed inputs
|
|
4. Exercise real IronClaw code paths, not just generic serde
