…1922) Removes /events/webhooks from PUBLIC_PATHS and extends the RPC auth middleware to accept the bearer either via the Authorization header (CLI clients) or a ?token=... query param (browser EventSource, which the WHATWG spec forbids attaching custom headers to). Both paths validate against the same in-process RPC token — single source of truth, no separate credential. Adds five integration tests covering unauthenticated, empty-value, wrong-value, valid-query, and valid-header paths. Closes the SSE subscription hole reported in tinyhumansai#1922: previously any local process able to reach 127.0.0.1:7788 could subscribe to all webhook deliveries with no credential.
- Exports getCoreRpcToken so SSE consumers can attach the bearer themselves (previously private to coreRpcClient). - Adds buildWebhookEventsUrl(baseUrl, token) — single seam that embeds the token as ?token=... in the /events/webhooks URL, or returns null when no token is available (caller should skip the EventSource rather than open an unauthenticated request the server will 401 and the browser will reconnect to forever). - Adds an EventTarget-based invalidation bus so any consumer caching the bearer in a long-lived connection (webhook SSE per tinyhumansai#1922) can drop and reopen it when clearCoreRpcTokenCache is called. All additive. Existing callers unaffected.
After restart_core_process the Tauri shell can mint a fresh OPENHUMAN_CORE_TOKEN for the new core process. Both FE wrappers around the IPC now call clearCoreRpcTokenCache() on success so the next getCoreRpcToken() re-resolves, and the invalidation bus wakes any long-lived SSE subscribers (per tinyhumansai#1922). Today CoreProcessHandle reuses the same Arc<String> token across restarts (see app/src-tauri/src/core_process.rs), so this is mostly future-proofing — but it costs ~3 LOC per call site and removes a latent staleness footgun for when the Tauri side does start rotating.
…inyhumansai#1922) useWebhooks and WebhooksDebugPanel now route /events/webhooks through buildWebhookEventsUrl, attaching the core RPC bearer as ?token=... EventSource cannot send Authorization headers, so the URL fallback matches the server-side allowlist added in the auth middleware. useWebhooks subscribes to the token-invalidation bus and re-runs its resolver, so a core restart (when it does rotate the token) tears down the old SSE and opens a fresh one with the new bearer. The EventSource is also skipped entirely when no token is available instead of opening an unauth request that the server will reject and the browser will reconnect to in a tight loop. WebhooksDebugPanel uses the same helper but keeps its mount-once effect (debug surface; reopening the panel re-establishes).
…mansai#1922) - buildWebhookEventsUrl: null/empty token guards + URL-encoding of reserved characters - useWebhooks: skips EventSource when no token resolved, constructs with ?token=<bearer> when one is, closes + reopens the EventSource on sessionToken flip, and reconnects when the invalidation bus fires (simulates restart_core_process clearing the cache without any sessionToken change)

Thanks for the review — dispositions on the 3 nitpicks:
|
…umansai#1922) Both restartCoreProcess wrappers (services/coreProcessControl and utils/tauriCommands/core) now have a Tauri-path test that asserts: 1. invoke('restart_core_process') runs once 2. clearCoreRpcTokenCache() runs after the invoke resolves (verified via invocationCallOrder so a concurrent getCoreRpcToken can't repopulate from the dead core before the new one mints a fresh bearer) Backfills coverage for the diff-cover >= 80% gate.
Adds a focused render test for the panel's mount-once SSE effect:
- constructs EventSource with `?token=<bearer>` once getCoreRpcToken
resolves
- skips EventSource entirely when no token is available (the path
that prevents an unauth request the server would 401 and the
browser would reconnect to forever)
- replays a `webhooks_debug` event and asserts the listener body
triggers a fresh logs + registrations reload via the tauri
commands
Provider chain (i18n, settings navigation, backend URL, tunnelsApi,
tauriCommands) mocked at the module boundary so the test isolates
the SSE-side observable behaviour and doesn't drag the full settings
shell into the render.
…1922) A rejected getCoreRpcToken() must not let the hook open an unauth SSE — it should fall through to the same "no token" branch as a null resolve. New test makes the mock reject and asserts the SSE effect never constructs EventSource.

…abbit review
Three patterns applied to the coverage tests added in this branch:
- **setTimeout → waitFor**: skip-EventSource branches in
WebhooksDebugPanel + useWebhooks tests no longer rely on a 10ms
real-time sleep. Instead waitFor settles on the observable
contract (resolver called + zero EventSource instances), so the
test is deterministic on slow CI.
- **Deferred promise for invoke resolve-order**: both
restartCoreProcess wrappers now use a manual-resolve Promise to
PROVE that clearCoreRpcTokenCache() does not fire until invoke()
actually resolves. invocationCallOrder alone could pass even if
the cache cleared before the IPC settled.
- **Save/restore EventSource global**: WebhooksDebugPanel teardown
restores any prior globalThis.EventSource instead of
unconditionally deleting, so the test does not leak state if a
sibling suite installs its own polyfill.

Walkthrough
Solid security fix that closes the unauthenticated SSE subscription hole on /events/webhooks (#1922). The implementation is clean: server-side removes the route from PUBLIC_PATHS, adds a tightly-scoped QUERY_TOKEN_PATHS allowlist with ?token=… fallback for browser EventSource (which can't set headers), and the FE wires the core RPC bearer through a shared buildWebhookEventsUrl helper with proper token-rotation plumbing. Test coverage is thorough — 7 unit tests for the Rust helpers, 5 E2E tests for the endpoint, and 8+ FE tests covering URL building, skip-on-null, reconnection on token rotation, and invalidation-bus fire.
No critical or major issues found. The design keeps a single source of truth for the bearer (no second credential), the QUERY_TOKEN_PATHS allowlist is intentionally narrower than PUBLIC_PATHS, and known limitations (token-in-URL for v1, /events still public, no per-restart rotation yet) are explicitly documented and scoped out.

Summary
/events/webhooksno longer bypasses the RPC auth middleware.Authorizationheader or — for browserEventSource, which the WHATWG spec forbids attaching custom headers to — a?token=…query param; both validate against the same in-process RPC token.buildWebhookEventsUrlhelper consumed by bothuseWebhooksandWebhooksDebugPanel, and subscribes to a new token-invalidation bus so an SSE stream torn down when the core RPC bearer rotates (e.g. afterrestart_core_process) reopens automatically with the fresh credential.Problem
useWebhooksandWebhooksDebugPanelopenedEventSource('/events/webhooks')with no credential, and the route was explicitly listed inPUBLIC_PATHSinsrc/core/auth.rs. Any local process able to reach127.0.0.1:7788(sandboxed agents, sibling apps, anything sharing the loopback) could subscribe to the live webhook delivery stream — registrations, payload metadata, debug logs — with no authentication.EventSourcecannot set custom headers (whatwg/html §10.7), so the existingAuthorization: Bearer …pattern used by every othercoreRpcClient.tscall is not directly transferable. The fix has to land the token through a transport thatEventSourceactually allows while keeping a single source of truth so we don't grow a second long-lived credential.Solution
Server (
src/core/auth.rs)/events/webhooksfromPUBLIC_PATHS.QUERY_TOKEN_PATHSallowlist + middleware fallback. When noAuthorizationheader is present and the path is in the allowlist, the middleware reads?token=…(URL-decoded viaurl::form_urlencoded) and validates it through the samebearer_matcheshelper used for the header path. Single source of truth — no separate credential, no second store.PUBLIC_PATHSso general read-only or upgrade-only routes don't accidentally inherit the relaxed transport.FE (
app/src/services/coreRpcClient.ts)getCoreRpcTokenso SSE consumers can attach the bearer themselves.buildWebhookEventsUrl(baseUrl, coreRpcToken)— returns the/events/webhooks?token=…URL, ornullwhen no token is available so the caller can skip the EventSource rather than open an unauthenticated request the server will 401 and the browser will reconnect to in a tight loop.EventTarget-based invalidation bus fired byclearCoreRpcTokenCache().FE consumers (
app/src/hooks/useWebhooks.ts,app/src/components/settings/panels/WebhooksDebugPanel.tsx)buildWebhookEventsUrl.useWebhooksresolves the bearer on mount and re-resolves onsessionTokenflips (login / logout / cloud-mode switch) and on invalidation-bus events. The SSE effect keys on the resolved bearer so a token change tears down the old EventSource and opens a fresh one.Cache invalidation on restart (
app/src/services/coreProcessControl.ts,app/src/utils/tauriCommands/core.ts)restart_core_processcallclearCoreRpcTokenCache()on success so any future Tauri-side rotation is reflected immediately.Tests

/events/webhooksis no longer subscribable without the per-launch core RPC bearer. Closes the lateral-listener vector from Security: SSE EventSource in useWebhooks.ts has no authentication #1922.Authorization: Bearercallers (CLI, scripts using~/.openhuman/core.token) keep working — both transports are accepted on the gated path.form_urlencodedparse per request to/events/webhooks. No effect onPOST /rpchot path (which never enters the query-token branch).Known limitations (intentional — out of scope for #1922)
EventSourceallows no other transport. Localhost-only loop, noReferer, no proxy — acceptable. v2 is a separate follow-up./events(the other SSE route) still bypasses auth. Same shape, different consumer; out of scope for this issue.restart_core_processdoes not currently rotate the token.CoreProcessHandle.rpc_tokenis anArc<String>minted once inCoreProcessHandle::new(); restart callsshutdown() + ensure_running()and reuses the same value. The FE invalidation-bus + reconnect plumbing fires correctly today but resolves to the same token. Wired now to future-proof v2 / any subsequent Tauri-side change that rotates per restart. Token rotation today requires a full app quit + relaunch (whole webview reloads).WebhooksDebugPanelkeeps a mount-once SSE effect (no token in dep array). Reopening the panel re-establishes; the panel is a debug surface and not held across long sessions.Related
