Disclosure summary
When `[migrations] ALLOWED_DOMAINS` was configured, a hostname matching the allow list was accepted without checking its resolved address against the local-network restrictions. A user who can start repository migrations and control the DNS of an allowed hostname could make it resolve to loopback or private addresses and bypass `ALLOW_LOCALNETWORKS = false`, reaching internal services from the Gitea server. Instances without `ALLOWED_DOMAINS` configured are not affected by this specific bypass.

This is not a complete index of GitHub or public exploit research. Coverage can also be limited by provider availability, rate limits, rejected metadata, incomplete search results, manual review, and the recorded refresh time.
