- Create server/src/utils/ssrfGuard.ts with checkSsrf() and createPinnedAgent()
- Resolves DNS before allowing outbound requests to catch hostnames that
map to private IPs (closes the TOCTOU gap in the old inline checks)
- Always blocks loopback (127.x, ::1) and link-local/metadata (169.254.x)
- RFC-1918, CGNAT (100.64/10), and IPv6 ULA ranges blocked by default;
opt-in via ALLOW_INTERNAL_NETWORK=true for self-hosters running Immich
on a local network
- createPinnedAgent() pins node-fetch to the validated IP, preventing
DNS rebinding between the check and the actual connection
- Replace isValidImmichUrl() (hostname-string check, no DNS resolution)
with checkSsrf(); make PUT /integrations/immich/settings async
- Audit log entry (immich.private_ip_configured) written when a user
saves an Immich URL that resolves to a private IP
- Response includes a warning field surfaced as a toast in the UI
- Replace ~20 lines of duplicated inline SSRF logic in the link-preview
handler with a single checkSsrf() call + pinned agent
- Document ALLOW_INTERNAL_NETWORK in README, docker-compose.yml,
server/.env.example, chart/values.yaml, chart/templates/configmap.yaml,
and chart/README.md
