fix(security): implement security review recommendations #5228
Conversation
This commit addresses all critical and high-priority recommendations from the security review: **Critical Fixes:** - Add nil checks before accessing memo properties in SetMemoAttachments and SetMemoRelations to prevent potential nil pointer dereference - Fix information disclosure in DeleteMemoReaction by returning consistent errors (now returns permission denied instead of not found to avoid revealing reaction existence) **Medium Priority Improvements:** - Add GetReaction() method to store interface for better performance (single reaction lookup instead of list operation) - Implement GetReaction() in all database drivers (SQLite, MySQL, PostgreSQL) - Update DeleteMemoReaction to use the new GetReaction() method **Test Coverage:** - Add comprehensive test coverage for SetMemoAttachments authorization checks - Add comprehensive test coverage for SetMemoRelations authorization checks - Add comprehensive test coverage for DeleteMemoReaction authorization checks - Add comprehensive test coverage for CreateUser registration enforcement All tests follow the same patterns as existing IDP service tests and cover: - Success cases for resource owners - Success cases for superuser/host users - Permission denied cases for non-owners - Unauthenticated access attempts - Not found scenarios Related to PR #5217 security review recommendations.
Code Review: Security Review Recommendations ImplementationThank you for addressing the security review recommendations! This PR makes important improvements to authorization checks and adds comprehensive test coverage. Overall, the implementation is solid, but I've identified a few issues that should be addressed before merging. Critical Issues1. SQLite GetReaction Missing sql.ErrNoRows HandlingLocation: The SQLite implementation of Problem: if err := d.db.QueryRowContext(ctx, ...).Scan(...); err != nil {
return nil, err // This returns sql.ErrNoRows instead of (nil, nil)
}
return reaction, nilExpected behavior: The method should return Fix: import "database/sql"
func (d *DB) GetReaction(ctx context.Context, find *store.FindReaction) (*store.Reaction, error) {
// ... existing where clause construction ...
reaction := &store.Reaction{}
if err := d.db.QueryRowContext(ctx, `
SELECT
id,
created_ts,
creator_id,
content_id,
reaction_type
FROM reaction
WHERE `+strings.Join(where, " AND ")+`
LIMIT 1`,
args...,
).Scan(
&reaction.ID,
&reaction.CreatedTs,
&reaction.CreatorID,
&reaction.ContentID,
&reaction.ReactionType,
); err != nil {
if err == sql.ErrNoRows {
return nil, nil
}
return nil, err
}
return reaction, nil
}This will cause the test Medium Priority Issues2. MySQL GetReaction Already ExistedLocation: The MySQL driver already had a Impact: No functional issue, but the PR description should clarify that only SQLite and PostgreSQL implementations were added. Low Priority / Style Issues3. Test Naming ConsistencyLocation: All new test files The test names follow a pattern like
This is more of a style preference and not a blocker. 4. Duplicate Code in GetReaction ImplementationsObservation: The PostgreSQL implementation of Not a blocker, but for future refactoring: Consider whether SQLite should follow the same pattern as PostgreSQL (reusing Positive Observations✅ Excellent test coverage - All critical paths are tested including owner, non-owner, superuser, and unauthenticated access ✅ Security fix for information disclosure - The ✅ Proper nil checks - The added nil checks in ✅ Consistent authorization patterns - The permission checks follow the established pattern of checking both ownership and superuser status ✅ Performance improvement - Adding ✅ Test patterns match existing code - The new tests follow the same structure as Recommendations
Test Coverage SummaryThe PR adds 691 lines of test code covering:
All tests follow proper patterns with success cases, permission denied cases, unauthenticated cases, and not found scenarios. Suggested Next Steps
Great work on the security improvements! Just need to fix that SQLite issue and this will be ready to merge. |
- Fix SQLite GetReaction to use standard List pattern (consistent with MySQL/PostgreSQL) - Add periods to comment endings (godot linter requirement) - Simplify GetReaction implementation to avoid sql.ErrNoRows handling
Security Review - PR #5228I've completed a comprehensive review of this security-focused PR. Overall, this is excellent work that addresses critical security issues with thorough testing. The implementation follows best practices and demonstrates a strong understanding of security principles. ✅ Strengths1. Critical Security Fixes

}✅ Proper error handling with appropriate gRPC status codes Security Implementation: ExcellentThe information disclosure fix is particularly well-implemented: // reaction_service.go:78-81
if reaction == nil {
// Return permission denied to avoid revealing if reaction exists.
return nil, status.Errorf(codes.PermissionDenied, "permission denied")

Authorization LogicThe authorization pattern is consistent and secure: if memo.CreatorID \!= user.ID && \!isSuperUser(user) {
return nil, status.Errorf(codes.PermissionDenied, "permission denied")
}✅ Owner-based access control 🐛 Potential Issues (Minor)1. MySQL GetReaction Already Uses GetReaction

- Use direct QueryRowContext with proper sql.ErrNoRows handling - Return nil when reaction is not found (sql.ErrNoRows) - Return error for other database errors - More performant than List approach (single row fetch vs list iteration)

💡 Recommendations1. Consider Direct Query for MySQL/PostgreSQL (Optional Performance Enhancement)For consistency with the SQLite implementation and optimal performance, consider implementing direct single-row queries in MySQL and PostgreSQL similar to SQLite's approach: // MySQL example
func (d *DB) GetReaction(ctx context.Context, find *store.FindReaction) (*store.Reaction, error) {
// Build direct QueryRowContext instead of ListReactions
// This matches SQLite's pattern and is more efficient
}However, the current approach is acceptable since:
