**Issue**: If a model implements custom `MarshalJSON()` method, the scanner won't detect ID exposure in the custom logic + - **Example**: + ```go + type User struct { + ID uint `json:"-" gorm:"primaryKey"` + } + + // ❌ Scanner won't detect this ID leak + func (u User) MarshalJSON() ([]byte, error) { + return json.Marshal(map[string]interface{}{ + "id": u.ID, // Leak not detected + }) + } + ``` + - **Mitigation**: Manual code review for custom marshaling, future enhancement to detect custom MarshalJSON + +2. **Map Conversions and Reflection**: + - **Issue**: Scanner can't detect ID leaks through runtime map conversions or reflection-based serialization + - **Example**: + ```go + // ❌ Scanner won't detect this pattern + data := map[string]interface{}{ + "id": user.ID, + } + ``` + - **Mitigation**: Code review, runtime logging/monitoring + +3. **XML and YAML Tags**: + - **Issue**: Scanner currently only checks `json:` tags, misses `xml:` and `yaml:` serialization + - **Example**: + ```go + type User struct { + ID uint `xml:"id" gorm:"primaryKey"` // Not detected + } + ``` + - **Mitigation**: Document as future enhancement (Pattern 7: XML tag exposure, Pattern 8: YAML tag exposure) + +4. **Multi-line Tag Handling**: + - **Issue**: Tags split across multiple lines may not be detected correctly + - **Example**: + ```go + type User struct { + ID uint `json:"id" + gorm:"primaryKey"` // May not be detected + } + ``` + - **Mitigation**: Enforce single-line tags in code style guide + +5. **Interface Implementations**: + - **Issue**: Models returned through interfaces may bypass detection + - **Example**: + ```go + func GetModel() interface{} { + return &User{ID: 1} // Exposed ID not detected in interface context + } + ``` + - **Mitigation**: Type-based analysis (future enhancement) + +### False Positive Scenarios + +1. **Non-GORM Structs with ID Fields**: + - **Mitigation**: Implemented GORM model detection heuristics (file location, gorm tag count, gorm.Model embedding) + +2. **External API Response Structs**: + - **Issue**: Structs that unmarshal external API responses may need exposed ID fields + - **Example**: + ```go + // This is OK - not a GORM model, just an API response + type GitHubUser struct { + ID int `json:"id"` // External API ID + } + ``` + - **Mitigation**: Use `// gorm-scanner:ignore` suppression comment + +3. **Test Fixtures and Mock Data**: + - **Issue**: Test structs may intentionally expose IDs for testing + - **Mitigation**: Exclude `*_test.go` files from scanning (configuration option) + +### Future Enhancements (Patterns 7 & 8) + +**Pattern 7: XML Tag Exposure** +- Detect `xml:"id"` on primary key fields +- Same severity and remediation as JSON exposure + +**Pattern 8: YAML Tag Exposure** +- Detect `yaml:"id"` on primary key fields +- Same severity and remediation as JSON exposure + +--- + +## Performance Benchmarking Plan + +### Benchmark Criteria + +1. **Execution Time**: + -
