## 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
