From f4b6c5af51eae992d8288d9483ca7e7ca6f3d060 Mon Sep 17 00:00:00 2001 From: liuhao1024 Date: Mon, 4 May 2026 14:02:04 +0800 Subject: [PATCH 1/2] fix(security): require dashboard auth for plugin API routes Remove the blanket /api/plugins/* exemption from auth_middleware so plugin API routes (e.g. Kanban dashboard) require the same session token as all other /api/ endpoints.

From e72b4d70526ca4f7a537855decb8bbbd2b757e41 Mon Sep 17 00:00:00 2001 From: Teknium <127238744+teknium1@users.noreply.github.com> Date: Sun, 10 May 2026 07:03:41 -0700 Subject: [PATCH 2/2] test(security): broaden plugin API auth coverage + correct stale docstring MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Follow-up to the previous commit's middleware fix. - plugins/kanban/dashboard/plugin_api.py: rewrite the "Security note" docstring. The previous text said "/api/plugins/ is unauthenticated by design" — that's now actively wrong and dangerously misleading. New text explains that plugin routes flow through the same session-token middleware as core API routes and that --host 0.0.0.0 is safe to use on a LAN as a result. - tests/hermes_cli/test_web_server.py: extend TestPluginAPIAuth to cover the surfaces the original PR didn't pin: * test_plugin_route_allows_auth now exercises a real plugin path (/api/plugins/example/hello) instead of accepting 200 OR 404 from a maybe-loaded kanban plugin — the assertion was effectively vacuous. * test_plugin_patch_requires_auth + test_plugin_delete_requires_auth cover non-GET mutation methods in case a future regression whitelists them by accident. * test_non_kanban_plugin_route_requires_auth proves the fix is plugin-agnostic, not kanban-specific (hits hermes-achievements + a non-existent plugin namespace; both 401 before route resolution). * test_plugin_websocket_unaffected_by_http_middleware locks in that the HTTP middleware change didn't accidentally start gating WS upgrades — kanban /events still uses its own ?token= check. Plus a cosmetic blank-line cleanup. --- plugins/kanban/dashboard/plugin_api.py | 27 +++++--- tests/hermes_cli/test_web_server.py | 86 +++++++++++++++++++++++--- 2 files changed, 95 insertions(+), 18 deletions(-) diff --git a/plugins/kanban/dashboard/plugin_api.py b/plugins/kanban/dashboard/plugin_api.py index 4cc2ccb3c3d55..cac563e94184b 100644 --- a/plugins/kanban/dashboard/plugin_api.py +++ b/plugins/kanban/dashboard/plugin_api.py @@ -13,15 +13,24 @@ Security note ------------- -The dashboard's HTTP auth middleware (``web_server.auth_middleware``) -explicitly skips ``/api/plugins/`` — plugin routes are unauthenticated by -design because the dashboard binds to localhost by default.
