Configuration Options (`starpunk/config.py`) + +Added three new configuration options with secure defaults: + +```python +# Debug file configuration (v1.5.0 Phase 2) +app.config["DEBUG_SAVE_FAILED_UPLOADS"] = os.getenv("DEBUG_SAVE_FAILED_UPLOADS", "false").lower() == "true" +app.config["DEBUG_FILE_MAX_AGE_DAYS"] = int(os.getenv("DEBUG_FILE_MAX_AGE_DAYS", "7")) +app.config["DEBUG_FILE_MAX_SIZE_MB"] = int(os.getenv("DEBUG_FILE_MAX_SIZE_MB", "100")) +``` + +**Key Decision**: Debug file saving is **disabled by default** (production-safe). + +### 2. Media Validation Updates (`starpunk/media.py`) + +Updated `validate_image()` function to: +- Check `DEBUG_SAVE_FAILED_UPLOADS` config before saving debug files +- Sanitize filenames to prevent path traversal attacks +- Use pattern: `"".join(c for c in filename if c.isalnum() or c in "._-")[:50]` + +**Security Fix**: Filename sanitization prevents: +- Path traversal (`../../../etc/passwd` → `...etcpasswd`) +- Special characters (`test<>:"|?*.jpg` → `test.jpg`) +- Overly long filenames (truncated to 50 chars) + +### 3. Cleanup Function (`starpunk/media.py`) + +Implemented `cleanup_old_debug_files(app)` with two-stage cleanup: + +**Stage 1 - Age-based cleanup**: +- Delete files older than `DEBUG_FILE_MAX_AGE_DAYS` +- Default: 7 days + +**Stage 2 - Size-based cleanup**: +- After age cleanup, check total size +- If exceeds `DEBUG_FILE_MAX_SIZE_MB`, delete oldest files first +- Default: 100MB limit + +**Algorithm**: +```python +1.
