- ✅ **Input Validation**: Implemented
- ✅ **Error Handling**: Enhanced with context

## Resolved Vulnerabilities

### ✅ Resolved: pyo3 0.20.3 → 0.27 (v0.1.0)

**Advisory ID:** RUSTSEC-2025-0020  
**Severity:** Critical  
**Issue:** Risk of buffer overflow in `PyString::from_object`  
**Previous Version:** 0.20.3  
**Current Version:** 0.27  
**Status:** ✅ RESOLVED  
**URL:** https://rustsec.org/advisories/RUSTSEC-2025-0020

**Resolution:**
- Upgraded pyo3 from 0.20.3 to 0.27 (fixes vulnerability)
- Migrated from pyo3-asyncio 0.20 to pyo3-async-runtimes 0.27 (required for pyo3 0.27 compatibility)
- Updated code to use pyo3 0.27 API (Bound types, Python::attach, etc.)

## Security Improvements (v0.1.0)

### Input Validation
- ✅ Path validation: All file paths are validated before use
  - Non-empty path check
  - Null byte detection (prevents path traversal via null bytes)
  - Validation occurs before any file operations

### Error Handling
- ✅ Enhanced error messages with file path context
  - Errors include the file path involved in the operation
  - Helps with debugging and security incident investigation
  - Provides better visibility into which files are affected by errors

## Security Practices

### Code Security
- ✅ No unsafe code blocks in codebase
- ✅ All code passes clippy security-focused lints
- ✅ Uses safe Rust APIs exclusively
- ✅ Input validation on all user-provided paths
- ✅ Enhanced error handling with operation context

### Dependency Management
- 🔄 Regular security audits recommended via `cargo audit`
- 🔄 Monitor for dependency updates
- 🔄 Update dependencies as part of regular maintenance

## Running Security Checks

### Cargo Audit
```bash
cargo install cargo-audit
cargo audit
```

### Clippy Security Lints
```bash
cargo clippy --lib --all-features -- -W clippy::suspicious -W clippy::correctness
```

### Check for Unsafe Code
```bash
grep -r "unsafe {" src/ --include="*.rs"
```

## Update Schedule

Security audits should be run:
- Before each release
- Weekly via automated CI/CD (see `.github/workflows/security.yml`)
- After any dependency updates
