RsyncGUI v1.7.0 — Security Audit & AI Backend Overhaul

What's New in v1.7.0

Security Hardening & Code Quality Audit

30 findings resolved across CRITICAL, HIGH, MEDIUM, LOW, and INFO severities.

Critical Fixes:

• API Keys to Keychain: All cloud AI backend API keys migrated from UserDefaults to macOS Keychain
• Shell Command Escaping: All rsync arguments properly escaped to prevent injection

High Fixes:

• Plist Injection Prevention: Schedule/job plist values validated against injection attacks
• Input Length Limits: Path and hostname inputs capped to prevent buffer abuse
• Race Condition Fix: Thread-safe job execution state management
• AI Backend Architecture: Complete overhaul — 6 new backend types, proper Swift extension patterns

Medium Fixes:

• Hostname validation with RFC-compliant regex
• Typed error enums replacing string-based errors
• Safe array access with bounds checking
• Proper pipe cleanup in rsync process management

Low/Info Fixes:

• Force unwrap elimination across 3 files
• Magic number extraction to named constants
• Locate button implementation (Finder reveal)
• MARK section comments for code organization
