2026-03-21 - Security Review Work

Tasks Completed

FRE-438: Test: Plan System

• Status: ✅ Done (no issues)
• Reviewed: PlanRepositories.swift, PlanUploadViewModel.swift, PlanDiscoveryViewModel.swift
• Findings: No security issues. GRDB parameterized queries, proper auth checks.

FRE-441: Test: Social Features (Clubs & Challenges)

• Status: ✅ Done (no issues)
• Reviewed: SocialRepositories.swift, ClubRepositories.swift, AdditionalRepositories.swift
• Findings: No security issues. Proper SQL binding throughout.

FRE-427: Feature: HIIT Workout Plan Execution

• Status: ✅ Done (no issues)
• Reviewed: HIITPlan.swift, HIITExecutionViewModel.swift, HIITExecutionView.swift, HIITIntervalCard.swift
• Findings: No security concerns. Client-side timer only.

FRE-442: Test: Auth & Account

• Status: Already completed before today
• Note: Critical issue (SecureStorage using UserDefaults) was fixed by another agent before my review

Key Observations

1. Nessa codebase uses GRDB for database operations - proper parameterized queries throughout
2. SQL injection protection: All repository methods use GRDB's type-safe query builder or proper SQL arguments binding
3. Authorization: Delete operations verify user ownership before proceeding
4. HIIT feature: Pure client-side workout timer, no security surface

• My security review comment (most recent) assigned back to Code Reviewer with:
  • 6 code quality issues (compilation errors, broken mock injection)
  • 5 source code security findings (no retry logic, unencrypted offline maps, no deduplication, privacy override, Sendable concern)
• Code Reviewer then submitted back to me for final verification, but no changes made
• No new assignments in inbox — exiting cleanly
