The DNS-rebinding guard (GHSA-cmhj-wh2f-9cgx) now also covers the provider dispatch path: for operator-supplied + base URLs (`providerSpecificData.baseUrl`, including `openai-compatible-*` nodes) the connection + is validated at connect time against the same guard mode as the URL check + (`dispatchGuarded()` in `open-sse/executors/dispatchPin.ts`), closing the classic TOCTOU window + on the highest-risk override path; it rides on the ambient patched `fetch` as a dispatcher and is + skipped whenever an outbound proxy, TLS impersonation or the direct sentinel applies, so + configured proxies and request logging are never bypassed. The rate limiter no longer fails fully open when Redis errors — it falls back to the in-memory limiter instead of allowing every request unconditionally. Boot now fails fast in production when `STORAGE_ENCRYPTION_KEY` is missing instead of silently persisting credentials in plaintext with only a warning, and the persisted `JWT_SECRET`/`API_KEY_SECRET` diff --git a/open-sse/executors/base.ts b/open-sse/executors/base.ts index 0dc9c60aa6ea..24593310d236 100644 --- a/open-sse/executors/base.ts +++ b/open-sse/executors/base.ts @@ -111,7 +111,7 @@ import { import { applyPeerTraceHeader } from "@/shared/resilience/peerRouting"; import { applyClineProtocolHeaders } from "@/shared/utils/clineAuth"; import { isProbeContext } from "@/shared/utils/probeOrigin"; -import { assertDispatchUrlAllowed, dispatchPinned } from "./dispatchPin.ts"; +import { assertDispatchUrlAllowed, dispatchGuarded } from "./dispatchPin.ts"; // Header helpers extracted to a pure leaf; re-exported for external importers // (executors + tests) that import them from "./base.ts". export { @@ -679,12 +679,17 @@ export class BaseExecutor { } try { - const response = await dispatchPinned(this.provider, url, { - method: "POST", - headers, - body: JSON.stringify(requestBody), - signal: activeSignal || undefined, - }); + const response = await dispatchGuarded( + this.provider, + url, + { + method: "POST", + headers, + body: JSON.stringify(requestBody), + signal: activeSignal || undefined, + }, + credentials + ); const text = await response.text(); if (!response.ok) { @@ -956,7 +961,12 @@ export class BaseExecutor { : requestOptions; try { - return await dispatchPinned(this.provider, requestUrl, optionsWithSignal); + return await dispatchGuarded( + this.provider, + requestUrl, + optionsWithSignal, + requestCredentials + ); } finally { if (timeoutId) clearTimeout(timeoutId); } diff --git a/open-sse/executors/dispatchPin.ts b/open-sse/executors/dispatchPin.ts index 6d6fdb4ada6e..8d272c348e62 100644 --- a/open-sse/executors/dispatchPin.ts +++ b/open-sse/executors/dispatchPin.ts @@ -1,11 +1,10 @@ import { isLocalProvider, isSelfHostedChatProvider } from "@/shared/constants/providers"; -import { getProviderValidationGuard } from "@/shared/network/outboundUrlGuardPolicy"; import { parseAndValidateNonMetadataUrl, parseAndValidatePublicUrl, } from "@/shared/network/outboundUrlGuard"; -import { resolveAndValidateAddresses } from "@/shared/network/dnsPin"; -import { createPinnedDispatcher } from "@/shared/network/dnsPinnedFetch"; +import { getProviderValidationGuard } from "@/shared/network/outboundUrlGuardPolicy"; +import { getGuardedDispatcher } from "../utils/connectGuardDispatcher.ts"; import { hasAmbientProxyContext, isDirectFetchContext, @@ -16,7 +15,7 @@ import { /** * String-level SSRF guard for the runtime dispatch path (GHSA-4f49-hj64-448x) — moved verbatim * from `BaseExecutor.assertOutboundUrlAllowed()` (which now delegates here) so the guard and the - * connect-time pin below live together and `base.ts` stays within its file-size ceiling. + * connect-time guard below live together and `base.ts` stays within its file-size ceiling. * Local / self-hosted providers are exempt; `public-only` blocks private + metadata, the default * mode blocks the cloud-metadata IMDS pivot.

The new execute() case proves both the fence (redirect lock, beforeFetch) and the guarded dispatcher reach the global fetch. rate-limiter-backup-flag-not-test-mode detected the Redis path through the old fail-open { allowed: true }. This PR makes a Redis failure fall back to in-memory limiting, so the test now observes the Redis path through the limiter's 'Redis eval failed' log, and the NODE_ENV=test case asserts Redis is never reached.
