From 1d723c5c21b0bbfbda6015481710e70355bd2aa3 Mon Sep 17 00:00:00 2001 From: Claude Date: Sat, 18 Apr 2026 16:00:19 +0000 Subject: [PATCH 1/9] feat: implement strict multi-surface access control MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Collapses ad-hoc auth into three router-level surfaces: public / No auth — home, A2A discovery, docs private /manage Tailscale-only (100.64.0.0/10) — admin UI, workbench api /api API key + hierarchical scopes (read/write) — M2M Key changes: - src/supervaizer/access/ — new package: client_ip.py (TRUSTED_PROXIES / XFF), tailscale.py (require_tailscale dep), api_auth.py (API_KEYS, require_api_key, require_scope); SUPERVAIZER_API_KEY preloaded as write - src/supervaizer/routers/ — public_router, api_router, private_router factories; router-level deps replace 14+ scattered Security() calls - admin/routes.py — removed verify_admin_access, console tokens, APIKeyHeader; Tailscale is the sole gate - routes.py / data_routes.py — removed per-route Security(); write-mutating endpoints get Depends(require_scope("write")) - server.py — replaced scattered include_router block + AdminIPAllowlistMiddleware with the three router factories - templates — global /admin → /manage; removed ?key= URL params and console-token JS; WebSocket workbench inherits Tailscale dep via private_router - tests — updated paths (/api/supervaizer/..., /manage/...); new test_access_client_ip.py, test_access_tailscale.py, test_access_api_auth.py; deleted test_admin_ip_allowlist.py (replaced) 457 tests pass; pre-existing boto3/docker failures unaffected. https://claude.ai/code/session_011Ansn4kxHVP8nLmLWESz36 --- src/supervaizer/access/__init__.py | 20 + src/supervaizer/access/api_auth.py | 85 ++++ src/supervaizer/access/client_ip.py | 65 +++ src/supervaizer/access/tailscale.py | 49 +++ src/supervaizer/admin/routes.py | 166 +------- src/supervaizer/admin/templates/agents.html | 12 +- .../admin/templates/agents_grid.html | 2 +- src/supervaizer/admin/templates/base.html | 11 +- .../admin/templates/case_detail.html | 8 +- .../admin/templates/cases_list.html | 12 +- .../admin/templates/cases_table.html | 6 +- src/supervaizer/admin/templates/console.html | 20 +- .../admin/templates/dashboard.html | 6 +- src/supervaizer/admin/templates/index.html | 2 +- .../admin/templates/job_detail.html | 6 +- .../admin/templates/jobs_list.html | 12 +- .../admin/templates/jobs_table.html | 6 +- .../admin/templates/navigation.html | 36 +- src/supervaizer/admin/templates/server.html | 6 +- .../admin/templates/workbench.html | 14 +- src/supervaizer/common.py | 15 + src/supervaizer/data_routes.py | 19 +- src/supervaizer/routers/__init__.py | 13 + src/supervaizer/routers/api.py | 57 +++ src/supervaizer/routers/private.py | 35 ++ src/supervaizer/routers/public.py | 63 +++ src/supervaizer/routes.py | 30 +- src/supervaizer/server.py | 92 ++--- tests/test_access_api_auth.py | 124 ++++++ tests/test_access_client_ip.py | 81 ++++ tests/test_access_tailscale.py | 122 ++++++ tests/test_admin_ip_allowlist.py | 139 ------- tests/test_admin_routes.py | 370 +++--------------- tests/test_routes_case_update.py | 20 +- tests/test_server.py | 29 +- tests/test_validation_endpoints.py | 2 + tests/test_workbench_routes.py | 6 +- 37 files changed, 938 insertions(+), 823 deletions(-) create mode 100644 src/supervaizer/access/__init__.py create mode 100644 src/supervaizer/access/api_auth.py create mode 100644 src/supervaizer/access/client_ip.py create mode 100644 src/supervaizer/access/tailscale.py create mode 100644 src/supervaizer/routers/__init__.py create mode 100644 src/supervaizer/routers/api.py create mode 100644 src/supervaizer/routers/private.py create mode 100644 src/supervaizer/routers/public.py create mode 100644 tests/test_access_api_auth.py create mode 100644 tests/test_access_client_ip.py create mode 100644 tests/test_access_tailscale.py delete mode 100644 tests/test_admin_ip_allowlist.py diff --git a/src/supervaizer/access/__init__.py b/src/supervaizer/access/__init__.py new file mode 100644 index 0000000..8808c2b --- /dev/null +++ b/src/supervaizer/access/__init__.py @@ -0,0 +1,20 @@ +# Copyright (c) 2024-2025 Alain Prasquier - Supervaize.com.
