Pull request overview
This PR updates the Tauri webview Content Security Policy (CSP) to permit connecting to remote “cloud runtime” cores over plain HTTP and WebSocket (ws://), addressing macOS runtime connection failures where connect-src blocked ws://<private-ip>:<port>.
Changes:
- Expand the desktop CSP
connect-srcallowlist inapp/src-tauri/tauri.conf.jsonto include thehttp:andws:scheme sources. - Extend
app/src/utils/tauriCsp.test.tsto parseconnect-srcand add a regression test assertinghttp:/ws:are allowed.

In `@app/src-tauri/tauri.conf.json`:
- Line 28: The CSP currently permits non-loopback plaintext HTTP transports,
allowing relay_http_rpc to send bearer credentials over cleartext. Restrict
credential-bearing remote endpoints to HTTPS/WSS and reject or exclude cleartext
http:// runtimes before credentials are sent, while preserving loopback
development transport support.
- Line 28: Define and reuse one explicit RPC destination-authorization policy
across imported configuration, testCoreRpcConnection, and relay_http_rpc;
validate the URL before selecting direct fetch or relay_http_rpc and before
sending RPC payloads or bearer tokens. Reject unauthorized HTTP(S) destinations
rather than relying on CSP scheme sources or rpcUrlNeedsShellRelay.

app/src/utils/configPersistence.ts:92
peekStoredRpcUrl()now mutates state by deleting the stored key when the value is disallowed. That side effect is surprising for a function named “peek”, and it also contradicts the docstring’s “peek … without falling back” intent (callers may reasonably expect an observational read). Consider either (a) renaming this function to reflect that it performs validation/cleanup, or (b) keepingpeekStoredRpcUrlside-effect free and doing cleanup ingetStoredRpcUrl()/storeRpcUrl()only.
export function peekStoredRpcUrl(): string | null {
try {
const stored = localStorage.getItem(RPC_URL_STORAGE_KEY);
if (stored && stored.trim().length > 0) {
const normalized = normalizeRpcUrl(stored);
if (isAllowedCloudRpcUrl(normalized)) return normalized;
localStorage.removeItem(RPC_URL_STORAGE_KEY);
}
app/src/components/BootCheckGate/tests/BootCheckGate.test.tsx:244
- This test no longer asserts the key behavioral guarantee: that
Continuewith a public cleartext HTTP URL does not proceed to run the boot check / confirm the mode. Right now it only checks that the UI stays on the picker screen, which could still be true even ifrunBootCheckfires (e.g. due to a race or an async error). Add an explicitexpect(mockRunBootCheck).not.toHaveBeenCalled()after clicking Continue to make the regression signal robust.
it('rejects public HTTP cloud URLs and directs users to HTTPS', () => {
renderGate();
fireEvent.click(screen.getByText('Run on the Cloud (Complex)'));
const urlInput = screen.getByPlaceholderText(/https:\/\/core\.example\.com/);
fireEvent.change(urlInput, { target: { value: 'http://core.example.com/rpc' } });
// The warning shows inline as soon as the public HTTP URL is typed.
expect(screen.getByText(/traffic will not be encrypted/i)).toBeInTheDocument();
fireEvent.change(screen.getByPlaceholderText(/Bearer token/i), {
target: { value: 'tok-1234' },
});
fireEvent.click(screen.getByRole('button', { name: 'Continue' }));
expect(screen.getByText(/traffic will not be encrypted/i)).toBeInTheDocument();
expect(screen.getByText('Select a Runtime')).toBeInTheDocument();
});
app/src/lib/bootCheck/index.ts:319
- In cloud mode, invalid URLs currently return the “not allowed” reason because
isAllowedCloudRpcUrl()is checked before parsing. That makes the “invalid URL” branch below effectively unreachable for malformed input (e.g."not a url"), which is less helpful for users and for debugging. Consider parsing first (to surface “not a valid URL”), then applyingisAllowedCloudRpcUrlfor the policy decision.
const normalizedUrl = normalizeRpcUrl(mode.url);
if (!isAllowedCloudRpcUrl(normalizedUrl)) {
logError('[boot-check] cloud mode — unauthorized URL, refusing to connect');
return { kind: 'unreachable', reason: 'Configured cloud URL is not allowed' };
}
app/src-tauri/src/core_rpc.rs:132
relay_http_rpcvalidates the URL and then immediately callspost_json_rpc, which performs the samevalidate_rpc_urlcheck again. This double-parse/double-validation is redundant; keeping the validation inpost_json_rpcalone preserves safety for all callers while avoiding duplication.
pub(crate) async fn relay_http_rpc(
url: String,
token: Option<String>,
body: String,
) -> Result<RelayHttpResponse, String> {
validate_rpc_url(&url)?;
post_json_rpc(&url, token.as_deref(), body).await
