Two small hardenings flagged by CodeQL:
- routes/registries.ts: drop the redundant startsWith block-list and rely
solely on URL parsing + protocol allow-list. The startsWith pass was
unreachable defense (any non-http/https scheme already fails the
protocol check below it) and was tripping js/incomplete-url-scheme-check.
- services/TemplateService.ts: replace the .includes('api.linuxserver.io')
substring match with new URL(registryUrl).hostname comparison. The
substring form would mis-classify a malicious admin-set URL like
https://evil.example/api.linuxserver.io/... as the LSIO registry and
apply the LSIO response parser to its payload. Hostname compare closes
that.
Behavioral parity for the happy path: every previously-accepted URL still
parses; the LSIO branch still triggers when the hostname is exactly
api.linuxserver.io.
Adds backend/src/utils/parseIntParam.ts with a shared parseIntParam
helper that writes a 400 'Invalid <label>' response and returns null on
non-numeric route params. Consolidates the parseInt + isNaN + 400 shape
that was inlined or duplicated across multiple routers.
Updated:
- routes/fleet.ts: replaced the local parseIdParam wrapper.
- routes/autoHeal.ts: replaced the local parsePolicyId wrapper.
- routes/notifications.ts: replaced parseRouteId wrapper plus an inline
notification-id site.
- routes/apiTokens.ts, routes/labels.ts, routes/registries.ts,
routes/scheduledTasks.ts, routes/users.ts: replaced inline copies.
Out of scope (route handlers without an existing isNaN check, kept
intentionally untouched to avoid introducing new 400 responses): alerts,
nodes, webhooks, and several user-routes handlers that rely on a
downstream 404 instead.
Closes#748
Move three more Round C route groups out of index.ts:
- /api/registries/* -> routes/registries.ts
- /api/system/{orphans,prune,docker-df,resources,images,volumes,networks,...} -> routes/systemMaintenance.ts
- /api/templates/* -> routes/templates.ts
Handlers moved verbatim. Middleware chains, response shapes, and error
messages are preserved. Registry scope-denial now uses the shared
rejectApiTokenScope helper (same payload shape).
index.ts drops from 2739 to 2130 lines. Remaining inline groups:
containers, stacks, security (Trivy/scans/SBOM/policies), and nodes.
