fix(webview): prevent CSP injection through OpenRouter URLs - #2422
Move the OpenRouter and Requesty lookups from the webview to the extension host. This removes user-configured URLs from the webview CSP.
The old CSP used openRouterBaseUrl in connect-src. A crafted URL could add CSP directives or markup in both the production and HMR webviews. Three webview hooks called fetch() directly, so the CSP needed provider origins.
Changes:
Add a requestProviderInfo message and a providerInfo reply with a request ID.
Add src/core/webview/providerInfoHandler.ts. It runs the three fetches with their zod schemas. It takes the API key and base URL from the message, so unsaved Settings values still work. It rejects unknown kinds and times out after 10 seconds. It returns a generic error without the configured URL.
Change useOpenRouterKeyInfo, useOpenRouterModelProviders and useRequestyKeyInfo to use the message. Hook signatures and fallbacks stay the same.
Remove the OpenRouter and Requesty origins from connect-src in both HTML builders. Delete webviewCsp.ts.
Reviewers should check the handler in providerInfoHandler.ts and the connect-src change in ClineProvider.ts.
Test Procedure
From the repository root, run:
cd src && pnpm vitest run core/webview
cd webview-ui && pnpm vitest run src/components/ui src/components/settings
pnpm check-types in packages/types, src and webview-ui
Manual check: open Settings with an OpenRouter key. Confirm the balance and the provider list load.
Validation results: step 1 passes 946 tests. Step 2 passes 1063 tests. Type checks and ESLint report no errors.
Pre-Submission Checklist
Issue Linked: This PR is linked to an approved GitHub Issue (see "Related GitHub Issue" above).
Scope: My changes are focused on the linked issue (one major feature/fix per PR).
Self-Review: I reviewed my own code with care.
Writing Style: The PR title and description use Simplified Technical English (ASD-STE100): short sentences, plain words, active voice, one idea per sentence, no contractions.
Testing: New and/or updated tests have been added to cover my changes (if applicable).
Test Helpers (test changes only): Shared test helpers (src/test-utils/, @/utils/test-utils) are used only for mechanical duplication; test intent and scenario-specific mocks remain visible.
Visual Snapshot (UI changes only): If a user would notice this change at a glance (layout, theme tokens, brand elements, empty/error states), I added or updated a *.visual.tsx snapshot in webview-ui/. See webview-ui/AGENTS.md → "When a UI change needs a snapshot".
Documentation Impact: I checked if my changes need documentation updates (see "Documentation Updates" section below).
The HMR builder still allows https://* and local http:// origins in connect-src. Those values do not come from user configuration, so this PR leaves them.
No actionable comments were generated in the recent review.
Summary
Summary by CodeRabbit
New Features
OpenRouter account details, model-provider information, and Requesty account details can now be retrieved through the extension host.
Security
Webview content security policies no longer include configured OpenRouter endpoints or the Requesty endpoint origin.
Provider lookups limit response sizes and avoid exposing untrusted endpoint hostnames in error logs.
Tests
Added coverage for provider information requests, returned data, failures, missing inputs, timeouts, response-size limits, and webview security policies.
Provider lookups now pass from webview hooks to the extension host, which fetches and validates provider responses and returns data or errors. OpenRouter endpoint responses have a 1 MiB limit. The HMR and built-webview CSPs no longer include configured provider origins.
Changes: Provider info flow
Layer / File(s)
Summary
Provider request contract and webview hooks packages/types/src/vscode-extension-host.ts, webview-ui/src/components/ui/hooks/*, webview-ui/src/components/ui/hooks/__tests__/*, webview-ui/src/utils/test-utils.tsx
Adds provider request and reply message types and a request helper with request-ID matching and a 20-second timeout. OpenRouter and Requesty hooks use the helper. Shared tests cover requests and hook behavior; the previous per-hook tests and stubTransport are removed.
Extension-host fetching and response handling src/core/webview/providerInfoHandler.ts, src/core/webview/webviewMessageHandler.ts, src/core/webview/__tests__/*providerInfo*, src/api/providers/fetchers/openrouter.ts, src/api/providers/fetchers/__tests__/openrouter.spec.ts
Adds provider response validation, 10-second fetch timeouts, bounded response reading, OpenRouter model-provider mapping, and handling for invalid kinds and fetch failures. OpenRouter endpoint requests set a 1 MiB response limit. The message handler dispatches provider-info requests to the new handler.
CSP policy and webview tests src/core/webview/ClineProvider.ts, src/core/webview/__tests__/ClineProvider.spec.ts
Removes configured OpenRouter origins from both CSPs and the explicit Requesty origin from the built-webview CSP. Tests check endpoint exclusion and count watchdog HTML generation.

Full details: Linked Issues check
Explanation
Directly linked issue #2460 is the only active target, so its coding requirements apply. The whole-PR summary (merge base 8254e11 to head 5d9ac31) establishes each requirement:
[#2460] Messages: requestProviderInfo and providerInfo (with request ID) are added in packages/types/src/vscode-extension-host.ts. webviewMessageHandler.ts routes requestProviderInfo to handleRequestProviderInfo.
[#2460] Host fetches: src/core/webview/providerInfoHandler.ts runs the OpenRouter key info, OpenRouter model providers, and Requesty key info fetches with their zod schemas. The API key and base URL come from the message, so unsaved Settings values work.
[#2460] Timeout and errors: host requests use a 10 second timeout. Failures post a generic error. Logs record the provider kind and error name, not the configured URL.
[#2460] Unknown kinds: the handler rejects unknown kinds, including __proto__ and constructor, with an error reply. providerInfoHandler.spec.ts covers this.
[#2460] Empty outcomes: missing keys return null. Schema failures return null or an empty map. Image-output models return an empty map. The spec covers these cases.
[#2460] Webview: requestProviderInfo.ts matches reply IDs, ignores other IDs, and times out. providerInfoHooks.spec.tsx covers these paths. The three hooks call this helper and keep their signatures and fallbacks.
[#2460] CSP: ClineProvider.ts removes the OpenRouter and Requesty origins from the built-webview connect-src. It removes the derived OpenRouter origin from the HMR connect-src. webviewCsp.ts is deleted. ClineProvider.spec.ts asserts that configured endpoints, including injected markup, are absent from the CSP in both builders.
Minor type note: the useOpenRouterKeyInfo and useRequestyKeyInfo result types no longer include null. Runtime null fallbacks remain, so the fallback requirement is met.
The HMR https://* and local http:// entries are not user-configured. They are outside #2460. The issue comment on host and port retention is not part of the issue body, so it is not applied here.
This assessment relies on the supplied summary. No focused code inspection was made.
Full details: Out of Scope Changes check
Explanation
All changed files connect to #2460 or to its tests.
ClineProvider.ts: removes the CSP origins and the OpenRouter origin helper. Its spec covers CSP exclusion.
providerInfoHandler.ts, webviewMessageHandler.ts, vscode-extension-host.ts, requestProviderInfo.ts, and the three hooks implement the message-based lookup.
src/api/providers/fetchers/openrouter.ts adds a 1 MiB response limit, a timeout option, and an untrustedBaseUrl option. The host handler uses these for its fetch. The summary states that trusted callers keep their prior logging and fallback behavior.
Deleted hook specs and stubTransport in webview-ui/src/utils/test-utils.tsx tested the removed direct fetch behavior. Their replacements are providerInfoHandler.spec.ts, providerInfoHooks.spec.tsx, webviewMessageHandler.providerInfo.spec.ts, and the new openrouter.spec.ts cases.
No changed file lacks a connection to #2460.
Full details: Regression Evidence
Explanation
Regression evidence is present for the changed behavior in PR #2422. The primary PR author is coderabbitai[bot]. The check does not depend on author identity. Changed behavior and matching coverage: - Host handler (src/core/webview/providerInfoHandler.ts): src/core/webview/__tests__/providerInfoHandler.spec.ts covers the default and custom OpenRouter and Requesty URLs, auth headers, missing apiKey and modelId (no request sent), schema-invalid bodies returning null with logging, the 1 MiB cap (exact-cap accepted, one byte over rejected, stream cancelled), failed status, non-JSON body, rejected fetch (no URL in logs), non-string params, and unknown kinds including __proto__ and constructor. - Endpoint fetcher (src/api/providers/fetchers/openrouter.ts): openrouter.spec.ts adds tests for image-output models, untrusted schema-invalid bodies (non-numeric context_length rejected, trusted fallback kept), a real-server streaming test bounding total time, the caller timeout, redacted error logs for untrusted URLs, and a missing endpoints list. - Webview hooks (requestProviderInfo.ts and the three hooks): providerInfoHooks.spec.tsx covers the payload and reply, out-of-order replies by request ID, host error rejection, mismatched IDs, 20 s timeout, listener and timer cleanup, missing-key and missing-model no-send paths, and host-error fallbacks with logging. Deleted hook tests are replaced by these. - CSP (ClineProvider.ts): ClineProvider.spec.ts checks both the production and HMR HTML builders with a hostile OpenRouter URL and a Requesty URL. It asserts that neither origin appears in the CSP, that there is one script-src, and that the payload is absent. The development-fallback expectation is updated. - Message routing: webviewMessageHandler.providerInfo.spec.ts covers an invalid kind and a valid Requesty request. - UI snapshot: the PR reports no user-visible layout or theme change, so no Playwright snapshot is required. Non-blocking gaps (not enough to fail under the stated criteria): - No test asserts the 10 s AbortSignal.timeout on the host key-info and Requesty fetches. The only related check is toBeInstanceOf(AbortSignal). This is close to mechanical configuration. - The 1 MiB maxContentLength on the model-providers path is verified by asserting the axios option, not by an oversize response through the endpoint fetcher. The handler-level cap test covers the shared readBoundedText path. Tests exercise behavior through the handler, hooks and HTML builders, not only implementation details. No changed behavior lacks a focused negative or error branch.
Full details: Security Boundaries
Explanation
The PR reduces the security surface. It removes the user-configured OpenRouter origin and the Requesty origin from both connect-src directives in src/core/webview/ClineProvider.ts, so configured values no longer enter the CSP. The new handler src/core/webview/providerInfoHandler.ts checks the kind with Object.hasOwn and validates params with a zod schema before any fetch. Responses are schema-validated before they reach the webview. Response bodies are capped at 1 MiB, requests have a 10 s timeout, and errors are logged by name only, without the configured URL. The getOpenRouterModelEndpoints changes add a body-size cap and redact the host in untrusted-URL error logs. Residual points I checked and do not count as failures under this check: - The handler forwards the webview-supplied baseUrl with the Authorization: Bearer key to the extension host fetch. The URL is not allowlisted. This is user-configured input, and the same key-to-configured-origin request already ran from the webview. The old CSP allowed that origin in connect-src, so no new key exposure path exists. - modelId is placed into the URL path without encoding. The endpoints request sends no credentials, and the same path construction existed in the removed hook. - The HMR CSP keeps https://*. The PR description says this allowance is not user-configured, and the change does not add it. No changed path leaks secrets or PII, executes unvalidated input, or bypasses an approval or allowlist control.
Full details: Persistence Integrity
Explanation
The "Persistence integrity" check fails only for a changed persistence path that can lose or corrupt state (an un-awaited write, a non-atomic write, missing rollback or partial-failure handling, or an unpropagated persisted default). I reviewed the changed-file inventory for PR #2422 and searched the changed hunks for persistence operations (globalState, workspaceState, secrets, .update(, file writes, rename, setState, persist, storage). The only match was a CSP meta-tag string literal, not a write. The substantive changes are: - src/core/webview/ClineProvider.ts: removes the OpenRouter origin derivation and the await this.getState() read from both HTML builders, and removes the Requesty and OpenRouter origins from connect-src. This is a read-only removal and writes no state. - providerInfoHandler.ts and the webview hooks: move HTTP lookups to the extension host with timeouts and schema validation. These are network reads and do not persist anything. - Type, message, and test changes. No changed code writes or persists state, so no changed persistence path exists for the listed failure conditions. The check passes.
Full details: Lifecycle Resource Cleanup
Explanation
The changed lifecycle paths release their resources on every exit path, so the "Lifecycle resource cleanup" failure condition is not met. - Webview request helper (webview-ui/src/components/ui/hooks/requestProviderInfo.ts): the message listener and the 20 s setTimeout are both removed in cleanup(). cleanup() runs on a matching reply and on timeout. Non-matching replies return early, and the timer bounds the wait. No leak. - Host handler (src/core/webview/providerInfoHandler.ts): every fetch uses AbortSignal.timeout(10 s), which is self-managing and needs no clear. readBoundedText calls reader.cancel() when the 1 MiB cap is exceeded. A normal end-of-stream exits the loop. No timer or stream is left open. - Endpoint fetcher (src/api/providers/fetchers/openrouter.ts): the timeout is AbortSignal.timeout through mergeAbortSignalAndTimeout(undefined, timeoutMs), which creates no external listener and no manual timer. maxContentLength is an axios option. Nothing new is attached to a long-lived signal. - Hooks (useOpenRouterKeyInfo, useOpenRouterModelProviders, useRequestyKeyInfo): they call requestProviderInfo inside react-query queryFn. They add no useEffect, subscription, interval, or listener. - ClineProvider.ts: the diff only removes CSP origins. It has no lifecycle-related lines. Possible "duplicate work after disposal" was considered. A host fetch that is already in flight can finish after the webview goes away. It is bounded by the 10 s timeout, and it matches the existing message-handler pattern. It is not a changed leak path.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Add a mixed-endpoint case for allowed hostnames with characters near the regex boundary.
The matrix covers many rejections. It has few accept cases with unusual hostnames. The accept path for hostnames that contain _, hyphens, or digits is not tested through either HTML builder. A regex narrowed by mistake would still pass these cases.
Add accept cases such as https://my-proxy_1.internal:8080/v1 and http://127.0.0.1:8080.

Add a three-row matrix that runs undefined, a rejected hostname and a
rejected protocol through getHtmlContent and getHMRHtmlContent. Each
case asserts the default origin appears in connect-src and the rejected
value does not. The accept-path test alone cannot catch a builder that
skips hostname or protocol validation.

- Line 111: Update the provider info test using fetchSpy and
jsonResponse(ENDPOINTS) to include both tagged and untagged endpoints in the
same response, then assert the complete provider map, including the untagged
endpoint’s endpoint.name-based entry. Keep the test focused on the handler’s

Review comments at @src/core/webview/providerInfoHandler.ts:
- Line 80: Update getJson to read response.body incrementally, count decoded
bytes, and cancel the reader and throw when the configured size limit—set above
the largest expected provider response—is exceeded; do not rely on
Content-Length. Preserve the existing error path so the handler posts its
generic failure reply, and add a test confirming an oversized body is rejected.

It takes the API key and base URL from the message, so unsaved Settings values still work. It rejects unknown kinds and times out after 10 seconds.
