From 9c184962424160d136a2049005fc451b3d4339d2 Mon Sep 17 00:00:00 2001 From: user Date: Sun, 26 Jul 2026 18:32:05 -0400 Subject: [PATCH] fix(security): close 3 RBAC and auth vulnerabilities from issue #431 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - S1: Remove POST /role_bindings from isAuthExempt — any authenticated user could create arbitrary role bindings without RBAC evaluation. Add bootstrap-admin Job using the existing seed-admin CLI command to break the chicken-and-egg problem for first admin provisioning. - S2: Add bearer token auth to sandbox /policy and /logs endpoints — these were completely unauthenticated, exposing sandbox state to any network caller. - S7: Reject service callers with empty JWT username instead of granting IsGlobalAdmin=true — the legacy fallback in both HTTP and gRPC RBAC middleware allowed privilege escalation via static tokens without OIDC identity.
