From a3e278feb3266ff5103061a662af9c1ac6baf42b Mon Sep 17 00:00:00 2001 From: "molecule-ai[bot]" <276602405+molecule-ai[bot]@users.noreply.github.com> Date: Fri, 17 Apr 2026 10:55:23 +0000 Subject: [PATCH] fix(security): add auth+ownership to PATCH /workspaces/:id (#680 #681) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ISSUE #680 — IDOR on PATCH /workspaces/:id: - Route was on the open router with no auth middleware. Any unauthenticated caller could rename, change role, or update any workspace field of any workspace ID without credentials (zero auth + no ownership check). - Fix: register under wsAuth (WorkspaceAuth middleware) which (a) requires a valid bearer token and (b) validates the token belongs to the target workspace, providing auth + ownership in a single check. - Remove the now-redundant in-handler field-level auth block — the middleware is a strictly stronger gate. Dead code gone. - Remove unused `middleware` import from workspace.go. - Update tests: two tests that asserted the old in-handler 401 are replaced by TestWorkspaceUpdate_SensitiveField_AuthEnforcedByMiddleware (documents that auth is now at the router layer); cosmetic-field test renamed. ISSUE #681 — test-token endpoint auth: - Confirmed: GET /admin/workspaces/:id/test-token already has middleware.AdminAuth(db.DB). No change needed — finding was from older state. Build: `go build ./...` clean. All 15 test packages pass.
