## Summary - Adds SSRF (Server-Side Request Forgery) protection to webhook requests by using the same secure axios adapter already used by HTTP workflow actions - Prevents webhooks from making requests to private/internal IP addresses (10.x, 192.168.x, 172.16-31.x, 169.254.x, localhost) - Adds specific error logging when a webhook fails due to SSRF protection ## Context The HTTP workflow tool (`HTTP_REQUEST` action) already had SSRF protection via `HTTP_TOOL_SAFE_MODE_ENABLED`, but webhooks were using `HttpService` directly without this protection. This inconsistency meant users could potentially configure webhooks to probe internal infrastructure. ### What's protected now: | Feature | Before | After | |---------|--------|-------| | HTTP Workflow Action | Protected (secure adapter) | Protected (secure adapter) | | Webhooks | **Unprotected** | Protected (secure adapter) | ### The secure adapter validates: 1. Protocol must be `http:` or `https:` 2. DNS resolution of hostname 3. Resolved IP must not be in private ranges ## Test plan - [ ] Configure a webhook with an external URL (e.g., `https://webhook.site`) - should work - [ ] Configure a webhook with `http://localhost:3000` - should fail with SSRF error in audit log - [ ] Configure a webhook with `http://10.0.0.1/test` - should fail with SSRF error in audit log - [ ] Configure a webhook with a domain that resolves to a private IP - should fail

Does the world need another CRM?
We built Twenty for three reasons:
CRMs are too expensive, and users are trapped. Companies use locked-in customer data to hike prices. It shouldn't be that way.
A fresh start is required to build a better experience. We can learn from past mistakes and craft a cohesive experience inspired by new UX patterns from tools like Notion, Airtable or Linear.
We believe in Open-source and community. Hundreds of developers are already building Twenty together. Once we have plugin capabilities, a whole ecosystem will grow around it.
