SUMMARY

Malicious or misconfigured client is sending requests with a spoofed Host header that isn't in ALLOWED_HOSTS. This is a security feature working as intended.

CHECK FIRST

Verify ALLOWED_HOSTS includes all legitimate domains. If the traffic is from bots, consider adding rate limiting.

AI Triage Real issue High confidence

SUMMARY

A user tried to register with an email address that already exists in the database. The signup view creates users without checking for existing accounts first.

LIKELY CAUSES

No uniqueness check before calling User.objects.create()
Missing form-level validation for duplicate emails

CHECK FIRST

Use get_or_create() or check User.objects.filter(email=email).exists()
Add a unique constraint validation message to the signup form

Fix one issue—not 500 duplicates.

Identical errors are grouped automatically by stack trace fingerprint.
