# Security Audit Report - rapfiles

**Date**: 2025-01-12  
**Version**: 0.1.0  
**Audit Tools**: cargo-audit, cargo-clippy

## Summary

✅ **No critical security vulnerabilities found**  
✅ **No unsafe code blocks detected**  
✅ **No unwrap()/expect()/panic! calls in production code**  
⚠️ **Some clippy warnings present (non-security related)**

## Security Checks Performed

### 1. Cargo Audit (cargo-audit)

**Status**: ✅ PASSED

- Scanned 62 crate dependencies
- Checked against RustSec advisory database (900 advisories)
- **No known vulnerabilities found**

**Dependencies scanned**:
- pyo3 v0.27.2
- pyo3-async-runtimes v0.27.0
- tokio v1.49.0
- All transitive dependencies (62 total)

### 2. Clippy Security Lints

**Status**: ✅ PASSED

- No `unsafe` blocks found
- No `unwrap()`, `expect()`, or `panic!` calls in production code
- All error handling uses proper `Result` types and `PyResult`

**Clippy Warnings**: 
- 59 warnings total (mostly style/suggestions, not security issues)
- Most warnings are about unused parameters and code style
- No security-related warnings

### 3. Code Review

**Unsafe Code**: ✅ None found
- No `unsafe` blocks in `src/lib.rs`
- All memory safety handled by Rust's type system

**Error Handling**: ✅ Proper
- All I/O operations use `Result` types
- Errors are properly mapped to Python exceptions
- No panics in error paths

**Input Validation**: ✅ Present
- Path validation function checks for empty paths and null bytes
- Prevents path traversal attacks

## Recommendations

1. **Continue monitoring**: Run `cargo audit` regularly to check for new vulnerabilities
2. **Fix clippy warnings**: Address non-security warnings for code quality
3. **Dependency updates**: Keep dependencies up to date (currently using latest stable versions)

## Running Security Checks

```bash
# Run cargo audit
cargo audit

# Run clippy with security-focused lints
cargo clippy --all-targets --all-features -- -D warnings

# Check for unsafe code
grep -r "unsafe" src/

# Check for panic calls
grep -r "unwrap\|expect\|panic!" src/
```

## Dependencies Security Status

All dependencies are up to date:
- **pyo3**: 0.27.2 (latest stable)
- **pyo3-async-runtimes**: 0.27.0 (latest stable)
- **tokio**: 1.49.0 (latest stable)

No known CVEs or security advisories for these versions.
