Angular < 20.3.27 Multiple Vulnerabilities

Synopsis

Angular < 20.3.27 Multiple Vulnerabilities

Description

According to its self-reported version number, Angular is prior to 20.0.0, 20.x prior to 20.3.27, 21.x prior to 21.2.19 or 22.x prior to 22.0.1. It is, therefore, affected by multiple vulnerabilities:

- A Cross-Site Scripting (XSS) vulnerability in the internationalization (i18n) pipeline of @angular/compiler. Event-handler attributes (such as onerror) can be marked for translation using i18n-on* attributes, allowing a malicious translation file to inject arbitrary JavaScript in the localized build. (CVE-2026-69151)

- An information disclosure vulnerability in @angular/service-worker. Sensitive request headers (such as Authorization) are not stripped on cross-origin redirects, allowing a remote attacker to obtain credentials by triggering a redirect to an untrusted origin. (CVE-2026-54264)

- A denial of service vulnerability in the formatDate function of @angular/common, also used by DatePipe. The length of the format parameter is not validated, allowing an excessively long format string to cause uncontrolled CPU and memory consumption. (CVE-2026-54268)

- A DOM clobbering vulnerability in the client hydration of @angular/core. The serialized transfer state is looked up using the predictable ng-state element identifier, allowing an attacker able to inject an element with this identifier to poison the hydration response cache. (CVE-2026-54267)

- A weak cache key hashing vulnerability in the HttpTransferCache of @angular/common. Cache keys are generated with a 32-bit hash, allowing an attacker to craft colliding request parameters so that an attacker-controlled response overwrites the response of a sensitive endpoint during SSR, leading to data leakage or state poisoning. (CVE-2026-54266)

- A sanitization bypass vulnerability in @angular/compiler. Security-sensitive native DOM properties (such as innerHTML, src or href) bound using the two-way binding syntax are emitted without sanitizer, leading to Cross-Site Scripting (XSS). (CVE-2026-54265)

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Angular version 20.3.27 or later.
