fix(gateway): role-gate agent execution and close /apps loopback bypass - #256
Merged

Conversation
/ws authenticated callers but never checked their role, so a viewer account token, viewer browser session, or OIDC user without an operator role claim could submit agent turns and approval decisions. REST submission (POST /api/integration/messages) already requires operator. Resolve the caller through AuthorizeOperatorRequest, the chain the HTTP API uses, and close connections below operator with 1008 (PolicyViolation). Closing after accept instead of a 403 handshake keeps web chat usable: browsers cannot read handshake status codes, and web chat already treats 1008 as an authorization failure rather than reconnecting. /ws/live is unchanged: it bridges the live model without the agent pipeline or tools. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
/ws was the first of several surfaces that authenticated callers but never checked their role. /v1/chat/completions, /v1/responses, A2A execution, /apps/chat, and the send_message/run_workflow/ respond_workflow MCP tools let any authenticated identity - viewer account tokens, viewer browser sessions, OIDC users without an operator role claim - run the agent with tools, while the REST routes they mirror require operator. New accounts default to viewer, so this was the common case rather than the edge case. All of them now go through EndpointHelpers.CanExecuteAgent, the role chain the HTTP API uses: - /v1/*: 403 with an OpenAI-style permission_error body. - A2A execution and /apps/chat: 403. /apps/chat also stops running the agent for an unauthenticated loopback client IP, which behind a same-host proxy without TrustForwardedHeaders was every caller. - MCP: only the three mutating tools fail, with a tool error result; read-only tools stay available to viewers. OpenClawWebSocketClient now raises OnClosed with the gateway's close status and reason, and Companion uses it to mark itself disconnected and show the reason instead of appearing connected after a 1008 close.

/apps/health, /apps/chat, and the /apps/mcp/{appId} proxy admitted any
request whose client IP was loopback, independent of the bind address
and AlwaysRequireAuth. Behind a same-host reverse proxy without
TrustForwardedHeaders every caller has a loopback IP, so these routes
answered unauthenticated requests: /apps/mcp served MCP App tool calls
and /apps/health leaked app details, even with AlwaysRequireAuth on.
Use the gateway's bind-based rule like every other endpoint: open only
on a loopback-bound gateway without AlwaysRequireAuth. Local MCP App
development on a loopback-bound gateway is unchanged.

Operator-role enforcement on agent execution surfaces is breaking for deployments whose accounts were left on the default viewer role, and admins had no way to see who was affected. - CanExecuteAgent logs each denial under OpenClaw.Gateway.Authorization with the surface (or MCP tool), auth mode, account, and role. The credential is never logged. - Security.AllowViewerAgentExecution (default false) restores the old behavior for authenticated identities below operator for one release. Every admission it grants is logged, and admin posture reports the viewer_agent_execution_allowed risk flag. Unauthenticated callers are still rejected.

New accounts default to viewer, and viewers can no longer chat or run the agent. The account form now shows what the selected role can do, starting with the viewer hint that clients which chat need operator. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
The /apps/mcp/{appId} proxy forwarded tools/call from any authenticated
role to the same upstream App session the agent uses, with a
caller-chosen _meta.sessionId. App tools can change state, and the only
legitimate client, an MCP App UI inside the /apps/chat host, already
requires operator.
tools/call now goes through CanExecuteAgent and returns a tool error
below operator; tools/list and resources stay available to any
authenticated role. The caller is read from the current request, so a
stateful session cannot inherit the identity that opened it.

Description
Several gateway surfaces check that a caller is authenticated but never check its role, so a viewer credential can run the agent with tools. The integration REST route for the same action (
POST /api/integration/messages) already requiresoperator, and the docs describevieweras read-only.Affected callers: viewer account tokens, viewer browser sessions, and OIDC users without an operator role claim. New operator accounts default to
viewer, and the admin UI's role dropdown starts onviewer, so this is the common case rather than an edge case.Separately, the
/apps/*routes trusted any loopback client IP. Behind a same-host reverse proxy withoutTrustForwardedHeaders, every caller has a loopback IP. These routes therefore answered unauthenticated requests, including MCP App tool calls through/apps/mcp/{appId}, and ignoredAlwaysRequireAuth.Summary
All surfaces that run the agent or mutate state now go through
EndpointHelpers.CanExecuteAgent, which resolves the caller with the sameAuthorizeOperatorRequestchain the HTTP API uses:operator/wsPOST /v1/chat/completions,POST /v1/responsespermission_errorbodyPOST /apps/chat/apps/mcp/{appId}tools/call/apps/chathost, already needsoperatoropenclaw.send_message,openclaw.run_workflow,openclaw.respond_workflow/apps/health,/apps/chat, and/apps/mcp/{appId}now follow the gateway's bind-based rule: open without credentials only on a loopback-bound gateway withAlwaysRequireAuthoff.Admin UI: the account form explains what the selected role can do. The default stays
viewer, and its hint says clients that chat needoperator.Client side:
OpenClawWebSocketClientgainsOnClosed(status, reason). Companion uses it to mark itself disconnected and show the gateway's reason. Before this, a 1008 close was swallowed and Companion kept showing "Connected".Performance: the fix for the double token verification these role checks introduce was pushed after this PR merged. It is in #261.
