Mirror the server HideForGuest flag on services: rename the field
(dropping the gorm default), invert userCanViewService so a service is
visible to guests by default and hidden only when HideForGuest is set,
and flip the public-stats filter in servicesentinel accordingly. Update
the visibility and permission-matrix tests to the new semantics.
Introduce Personal Access Tokens (nzp_*) as a stateless auth path alongside
JWT, gated per-endpoint by a scope middleware (nezha:{resource}:{verb}) with
fail-closed empty-scope defaults and a server-id whitelist. Self-management
endpoints (profile, api-tokens, oauth2 bind, refresh-token) explicitly reject
PATs to block privilege-escalation chains. A revoke registry tears down active
long-lived connections (terminal, fm, ws, transfer, mcp) the moment a PAT is
deleted, with a tombstone closing the revoke->register race.
Add an MCP endpoint that proxies tool calls (exec, fs read/write/delete,
transfer) to agents over gRPC, guarded by origin/DNS-rebinding checks, a
per-token rate limiter, audit logging, and a kill switch. Serialize all
sends through the IOStream wrapper to honour grpc-go's concurrency contract.
Add CSRF double-submit protection on unsafe cookie-authenticated methods,
exempting authenticated PAT requests by context identity (not a forgeable
Authorization header). Apply visibility/whitelist filtering consistently
across list, get-by-id, and mutate paths to enforce tenant isolation.
Migrate legacy mcp:* scopes: rewrite read/exec to nezha:* equivalents and
drop dangerous write/delete/wildcard grants.

GHSA-vrmh-5mmx-hjwx: GET /api/v1/server/:id/service and
GET /api/v1/service/:id/history both iterate the raw service list and
emit ServiceName / timing for any service that happens to monitor the
queried server, ignoring the owner's EnableShowInService=false flag.
Both routes are on optionalAuth, so unauthenticated visitors could
enumerate hidden services by name and timing.
Introduce userCanViewService(c, service):
- EnableShowInService=true -> always visible
- admin -> always visible
- authenticated owner -> visible (HasPermission)
- everyone else -> hidden
getServiceHistory rejects unknown-or-invisible service with the same
'service not found' message so the endpoint cannot be used as an
oracle. listServerServices pre-filters the sorted service list.
Owners and admins keep their existing visibility into their own hidden
services.
Tests:
- TestUserCanViewServiceVisibleServiceIsPublic
- TestUserCanViewServiceHiddenServiceRejectsGuest
- TestUserCanViewServiceHiddenServiceRejectsForeignMember
- TestUserCanViewServiceHiddenServiceAllowsOwner
- TestUserCanViewServiceHiddenServiceAllowsAdmin
