From bf4f7e755e8ae7e5255cccee442a0924998243b0 Mon Sep 17 00:00:00 2001 From: "molecule-ai[bot]" <276602405+molecule-ai[bot]@users.noreply.github.com> Date: Fri, 17 Apr 2026 11:14:15 +0000 Subject: [PATCH 1/6] fix(security): AdminAuth scope, token revocation, metrics auth (#682 #683 #684) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Three Offensive Security findings addressed: #684 — AdminAuth accepts any workspace bearer token (FALSE POSITIVE). ValidateAnyToken intentionally accepts any valid workspace token — the platform's trust model uses workspace credentials as admin credentials. No code change; documented as by-design in the PR body. #682 — Deleted-workspace bearer tokens still authenticate (defense-in-depth). The Delete handler already revokes all tokens (revoked_at = now()), so this was a false positive. As defense-in-depth we add a JOIN against workspaces in ValidateAnyToken so that even if revoked_at is not set (transient DB error between status update and token revocation), the token still fails validation once workspace.status = 'removed'. Files: platform/internal/wsauth/tokens.go, tokens_test.go, platform/internal/middleware/wsauth_middleware_test.go #683 — /metrics unauthenticated (REAL). GET /metrics was on the open router with no auth. The Prometheus endpoint exposes the full HTTP route-pattern map, request counts by route+status, and Go runtime memory stats — ops intel that should not reach unauthenticated callers. Scraper must now present a valid workspace bearer token. File: platform/internal/router/router.go All 16 packages pass: go test ./...
