`I18nSelectPipe.transform()` called `mapping.hasOwnProperty()` directly,
which fails in two edge cases:
- Mappings created with `Object.create(null)` have no prototype and
therefore no `hasOwnProperty` method, causing a TypeError at runtime.
- Mappings where a key literally named `hasOwnProperty` shadows the
built-in method return incorrect results silently.
Replace both call sites with `Object.hasOwn(mapping, key)`, which
delegates through `Object` directly and is immune to both issues.
Add two regression tests that demonstrate the broken behaviour before
the fix and pass after it.
Skip HttpTransferCache serialization for HTTP responses that contain a
Set-Cookie header.
Cookie-setting responses commonly represent session-specific,
user-specific, or security-sensitive state. Serializing their bodies into
SSR TransferState can embed sensitive data into the generated HTML, where
it may be reused during hydration or replayed by a shared cache/CDN.
Serialize transfer cache request parameters without comma-joining repeated values so distinct HttpClient requests cannot reuse the same cached response.
`findAnchorFromDocument` interpolates the raw url fragment into
`[name="${target}"]` for the shadow DOM lookup, so a fragment reachable
through the router when `anchorScrolling` is on can break out of the
attribute selector and make `querySelector` throw or match unrelated
nodes, and it also breaks legitimate anchor names containing a quote.
Wrap the value in `CSS.escape` so it stays a single attribute-value token.
Replace `in` operator with `Object.hasOwn` in
formatDateTime to prevent prototype pollution attacks.
The `in` operator traverses the prototype chain, meaning a polluted
Object.prototype key could be picked up as a valid replacement value.
This is especially critical in SSR environments where a single
prototype pollution attack persists across all subsequent requests in
the shared Node.js process, potentially injecting malicious content
into every user's rendered HTML.
Using `Object.hasOwn` restricts the lookup to
own properties only, blocking prototype chain traversal.
The `escapeCssUrl` helper used by `NgOptimizedImage` to sanitize placeholder URLs for use in the `background-image` CSS property previously escaped only backslashes and double quotes. However, several characters that can terminate a CSS quoted string according to the CSS Syntax Level 3 specification were left unescaped, allowing a crafted placeholder URL to break out of the `url("...")` context and inject arbitrary CSS.
This change additionally escapes the following characters using CSS hex escapes:
* `U+000A` (LINE FEED) → `\A `
* `U+000D` (CARRIAGE RETURN) → `\D `
* `U+000C` (FORM FEED) → `\C `
* `U+0000` (NULL) → `\0 `
For example:
```text id="1w5vkp"
x.com/img\nx.jpg → x.com/img\A x.jpg
x.com/img\rx.jpg → x.com/img\D x.jpg
x.com/img\fx.jpg → x.com/img\C x.jpg
x.com/img\0x.jpg → x.com/img\0 x.jpg
```
The trailing space is required by the CSS tokenizer to terminate the escape sequence and prevent the following character from being interpreted as part of the escape.
The backslash replacement remains first in the chain to avoid double-escaping the backslashes introduced by subsequent replacements.
Preserve `referrer: ''` when constructing and cloning HttpRequest.
An empty string is a valid Fetch referrer value and is documented by
Angular as the way to omit referrer information for sensitive requests.
The previous truthy checks treated it as if the option was not provided,
causing requests to fall back to the browser default referrer behavior.
Replace the custom 64-bit non-cryptographic combined DJB2 hashing implementation in HttpTransferCache with a robust, pure JavaScript, synchronous SHA-256 algorithm.
Introduces a maximum length of 256 characters for date format strings.
This prevents potential Denial of Service (DoS) attacks by throwing an
`INVALID_DATE_FORMAT` error if an excessively long format string is
provided to `formatDate` or `DatePipe`, safeguarding against performance
degradation or application crashes.
JSONP is deprecated because it is prone to Cross-Site Scripting (XSS) attacks. Since JSONP works by executing arbitrary scripts in the global context, it bypasses modern Content Security Policies (CSP) and can lead to severe security vulnerabilities if the server or endpoint is compromised.
DEPRECATED: `HttpClient.jsonp`, `HttpClientJsonpModule`, and related JSONP classes/functions are deprecated. Use standard HTTP requests instead.
Previously, when making an HTTP request where the URL contained a fragment (`#`) and `HttpParams` were provided, the parameters were appended to the very end of the URL (after the fragment). This resulted in the parameters being treated as part of the fragment rather than query parameters, potentially bypassing server-side logic and validation.
This commit updates the URL parsing logic in `HttpRequest` to split the URL by the fragment, correctly inserting the query string before any fragment.
Do not store HTTP transfer cache entries when either the request or response
uses `Cache-Control: no-store`, `Cache-Control: private`, or
`Cache-Control: no-cache`.
Also skip transfer cache when requests use the Fetch API `cache` option with
`no-store` or `no-cache`.
Because transfer cache serializes SSR HTTP responses into the rendered HTML,
Angular now treats these directives conservatively to avoid exposing sensitive
or explicitly uncacheable data through `TransferState`.
PR Close#69017
Treat HttpClient requests using `credentials: 'include'` and `same-origin` as credentialed
when deciding whether a response can be stored in the HTTP transfer cache.
The transfer cache already skips requests with `withCredentials`, `Cookie`,
`Authorization`, or `Proxy-Authorization` because those responses may contain
user-specific data. Fetch-backed requests can express the same credentialed
behavior through the `credentials` option, so these responses must not be
serialized into the SSR HTML.
This keeps credentialed SSR responses out of TransferState and aligns the
cache eligibility check with the fetch request options supported by HttpClient.
PR Close#69017
Hit this while exercising `Location.normalize` with route paths that end in non-`.html` suffixes.
The unescaped `.` in the strip regex inside `_stripIndexHtml` matches any character, so e.g. `/foo/indexXhtml` and `/foo/index_html` both collapse to `/foo` before the base-path strip and end up resolving to the wrong route.
Escape the dot so only the literal `/index.html` suffix is stripped.
By default, the `FetchBackend` on SSR will limit the response body size to 10 MB.
If the response body exceeds this limit, an error will be thrown.
This default value can be configured by providing by setting the `maxResponseBodySize` in `provideServerRendering`.
This is to prevent DoS on the server when loading large files
Update the transfer cache check to safely exclude all requests sent with the `withCredentials` flag.
By default, the HTTP transfer cache avoids caching user-specific responses to prevent sensitive data exposure or incorrect caching. While requests with explicit headers like `Cookie` or `Authorization` are excluded by default, requests can also be sent with credentials via the `withCredentials` flag without having those headers explicitly declared on the request object.
To keep user-specific responses from being cached, exclude `withCredentials` requests unconditionally, even when the `includeRequestsWithAuthHeaders` option is set to true.
Treat requests with a Cookie header like other auth-bearing requests and skip TransferCache caching them by default.
This preserves the explicit opt-in path via includeRequestsWithAuthHeaders, adds regression coverage for cookie-bearing requests, and updates the SSR guide to document the behavior.
Update the minimum supported Node.js versions for v22 and v24. Specifically, the minimum supported version for Node.js v22 is bumped to v22.22.3, and for v24 it is bumped to v24.15.0. This ensures compatibility with newer runtime versions and coordinates ranges across monorepo packages.
Marks `HttpResourceRequest`, `HttpResourceOptions`, and `HttpResourceRef` as public APIs following the stabilization of the Resource API in https://github.com/angular/angular/pull/68253
Updates the supported Node.js engine versions to include Node.js 26.
This allows running the CLI on Node.js 26.0.0 and above while continuing to support active LTS versions.
The time has come.
Note: #67382 introduced a breaking change where you could notice some sublte timing change on how `value` is set when using `rxResource` or a `stream` on a `resource`
In order to raise an error on upload progress on the `FetchBackend`, we split `reportProgress` into 2 respective properties.
DEPRECATED: The `reportProgress` option is deprecated please use `reportUploadProgress` & `reportDownloadProgress` instead.
Focus the target element using `focus({preventScroll: true})` after scrolling, so the browser doesn’t adjust the scroll position when applying focus.
Fixes#65938
Add support for CSP nonces in JsonpClientBackend by injecting the CSP_NONCE token.
This ensures that dynamically created script tags for JSONP requests include the
required nonce attribute to comply with strict Content Security Policies.
The `HttpClient` tests in `client_spec.ts` were failing intermittently in Node/Domino environment because `MockPlatformLocation` defaults to `http://_empty_/`. This valid URL satisfied the URL parser in `xsrfInterceptorFn`, causing it to proceed to cookie extraction which throws `NotYetImplemented` in Domino.
To fix this:
1. Disabled XSRF protection in `client_spec.ts` using `withNoXsrfProtection()`, as these tests are not for XSRF.
2. Provided `ɵprovideFakePlatformNavigation` to remove state leakage effects and ensure consistency.
Replaced testing constructions of `Date` objects from `formatDate` tests from plain ISO strings over to 'new Date(year, month, date)'.
Instantiating 'new Date("2024-01-01")' parses the string strictly as UTC midnight ("2024-01-01T00:00:00.000Z"). When local operations execute (such as calculating `getThursdayThisIsoWeek` boundaries), the UTC date shifts relative to the executing machine's timezone. For example, in PST (GMT-8), that date translates exactly to 'December 31st 16:00:00', pushing week boundaries backwards.
By wrapping date constructs explicitly as 'new Date(2024, 0, 1)', it natively guarantees local midnight execution and prevents boundaries shifting on global CI Remote Build Execution (RBE) workers.
Example (from a machine in PST):
```javascript
> new Date('2024-01-01')
Sun Dec 31 2023 16:00:00 GMT-0800 (Pacific Standard Time)
> new Date(2024, 0, 1)
Mon Jan 01 2024 00:00:00 GMT-0800 (Pacific Standard Time)
```
Removes the 'America/New_York' timezone string test case from `formatDate` tests because the underlying `Date.parse` API does not support IANA timezone strings. This caused the timezone calculation to silently fall back to the local executing machine's timezone, leading to non-deterministic test flakiness on Remote Build Execution (RBE) workers operating in varying geographic locations.
The default change detection strategy is now OnPush.
BREAKING CHANGE: Component with undefined `changeDetection` property are now `OnPush` by default. Specify `changeDetection: ChangeDetectionStrategy.Eager` to keep the previous behavior.
