From c1656503efa9e40fc61aa7079d156767b7c20987 Mon Sep 17 00:00:00 2001 From: Dev Lead Agent Date: Tue, 14 Apr 2026 06:33:22 +0000 Subject: [PATCH 1/2] fix(security): protect global secrets routes with AdminAuth middleware (Cycle 7) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Three unauthenticated routes allowed arbitrary read/write/delete of all global platform secrets (API keys, provider credentials) with zero auth: - GET/PUT/POST /settings/secrets - DELETE /settings/secrets/:key - GET/POST/DELETE /admin/secrets (legacy aliases) Fix: new AdminAuth middleware with same lazy-bootstrap contract as WorkspaceAuth — fail-open when no tokens exist (fresh install / pre-Phase-30 upgrade), enforce once any workspace has a live token. Any valid workspace bearer token grants access (platform-wide scope, no workspace binding needed). Changes: wsauth/tokens.go — HasAnyLiveTokenGlobal + ValidateAnyToken functions wsauth/tokens_test.go — 5 new tests covering both new functions middleware/wsauth_middleware.go — AdminAuth middleware router/router.go — global secrets routes now registered under adminAuth group Co-Authored-By: Claude Sonnet 4.6 --- .../internal/middleware/wsauth_middleware.go | 35 ++++++++ platform/internal/router/router.go | 20 ++--- platform/internal/wsauth/tokens.go | 39 +++++++++ platform/internal/wsauth/tokens_test.go | 79 +++++++++++++++++++ 4 files changed, 164 insertions(+), 9 deletions(-) diff --git a/platform/internal/middleware/wsauth_middleware.go b/platform/internal/middleware/wsauth_middleware.go index 52cf0d8b..e74aefac 100644 --- a/platform/internal/middleware/wsauth_middleware.go +++ b/platform/internal/middleware/wsauth_middleware.go @@ -49,3 +49,38 @@ func WorkspaceAuth(database *sql.DB) gin.HandlerFunc { c.Next() } } + +// AdminAuth returns a Gin middleware for global/admin routes (e.g. +// /settings/secrets, /admin/secrets) that have no per-workspace scope. +// +// Same lazy-bootstrap contract as WorkspaceAuth: if no live token exists +// anywhere on the platform (fresh install / pre-Phase-30 upgrade), requests +// are let through so existing deployments keep working.
