Replace node-fetch v2 with Node 22's built-in fetch API across the entire server.
Add undici as an explicit dependency to provide the dispatcher API needed for
DNS pinning (SSRF rebinding prevention) in ssrfGuard.ts. All seven service files
that used a plain `import fetch from 'node-fetch'` are updated to use the global.
The ssrfGuard safeFetch/createPinnedAgent is rewritten as createPinnedDispatcher
using an undici Agent, with correct handling of the `all: true` lookup callback
required by Node 18+. The collabService dynamic require() and notifications agent
option are updated to use the dispatcher pattern. Test mocks are migrated from
vi.mock('node-fetch') to vi.stubGlobal('fetch'), and streaming test fixtures are
updated to use Web ReadableStream instead of Node Readable.
Fix several bugs in the Synology and Immich photo integrations:
- pipeAsset: guard against setting headers after stream has already started
- _getSynologySession: clear stale SID and re-login when decrypt_api_key returns null
instead of propagating success(null) downstream
- _requestSynologyApi: return retrySession error (not stale session) on retry failure;
also retry on error codes 106 (timeout) and 107 (duplicate login), not only 119
- searchSynologyPhotos: fix incorrect total field type (Synology list_item returns no
total); hasMore correctly uses allItems.length === limit
- _splitPackedSynologyId: validate cache_key format before use; callers return 400
- getImmichCredentials / _getSynologyCredentials: treat null from decrypt_api_key as
a missing-credentials condition rather than casting null to string
- Synology size param: enforce allowlist ['sm', 'm', 'xl'] per API documentation
Node 20+ enables autoSelectFamily by default, causing internal dns lookups
to be called with `all: true`. This expects the callback to receive an array
of address objects instead of a flat (address, family) pair, causing webhook
requests to fail with "Invalid IP address: undefined".
* add test suite, mostly covers integration testing, tests are only backend side
* workflow runs the correct script
* workflow runs the correct script
* workflow runs the correct script
* unit tests incoming
* Fix multer silent rejections and error handler info leak
- Revert cb(null, false) to cb(new Error(...)) in auth.ts, collab.ts,
and files.ts so invalid uploads return an error instead of silently
dropping the file
- Error handler in app.ts now always returns 500 / "Internal server
error" instead of forwarding err.message to the client
* Use statusCode consistently for multer errors and error handler
- Error handler in app.ts reads err.statusCode to forward the correct
HTTP status while keeping the response body generic
- 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
