Greptile Summary

This PR consolidates multiple security, performance, and UX improvements across 9 merged PRs. The changes significantly strengthen the application's security posture through comprehensive authentication checks, SQL/NoSQL injection prevention, and CSP hardening while adding useful features like one-click unsubscribe and OpenGraph images.

Key Changes

• Security hardening: Added authentication and permission checks to previously unprotected API routes (/api/jobs, /api/memory, /api/templates), created reusable permission helper functions, and implemented comprehensive SQL/NoSQL injection prevention for MySQL, PostgreSQL, and MongoDB query tools
• CSP improvements: Restricted localhost URLs to development mode only, preventing accidental exposure in production environments
• Path traversal protection: Enhanced SSH tool with extensive path traversal validation covering URL-encoded and multi-encoding attack vectors
• One-click unsubscribe: Implemented RFC 8058-compliant one-click unsubscribe supporting both JSON and form-urlencoded requests with proper email headers
• OpenGraph images: Added infrastructure for uploading, storing, and serving OG images for templates with client-side capture utilities
• Performance optimization: Added database indexes for common access patterns (api_key, verification, workflow_blocks)
• Slack improvements: Enforced 15-message read limit and removed duplicate canonicalParamId fields that were causing parameter conflicts
• HITL enhancements: Allowed human_in_the_loop blocks to reference their own URL output in tag dropdowns
• Jira tool expansion: Added support for labels, due dates, reporters, environments, and custom fields

Confidence Score: 5/5

• This PR is safe to merge with excellent security improvements and minimal risk
• The PR demonstrates high-quality security engineering with comprehensive input validation, proper authentication/authorization patterns, and defensive programming practices. All security-critical changes follow established patterns, validation logic is thorough without being overly restrictive, and the changes are well-tested according to the PR descriptions. The only minor issue is a style preference for parameter visibility in the Jira tool.
• No files require special attention - all changes follow security best practices
