SCA: security update for @angular/core (GHSA-rgjc-h3x7-9mwg)

high Tenable Cloud Security Plugin ID 443216

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Angular is a development platform for building mobile and desktop web applications using
 TypeScript/JavaScript and other languages. Prior to 22.0.1, 21.2.17, and 20.3.25, to optimize client-side
 bootstrap in Server-Side Rendered (SSR) environments, Angular supports Hydration via
 provideClientHydration(). During SSR, Angular serializes the application's runtime state (such as cached
 HttpClient responses) and outputs it into the HTML stream as a <script> tag with a predictable identifier.
 During client bootstrap, Angular recovers this state by looking up the element via
 document.getElementById('ng-state') and parsing its text content. Because the DOM element lookup for the
 state container is predictable and relies solely on the ID selector (ng-state), it is susceptible to DOM
 Clobbering. If the application binds untrusted user input or CMS content to element properties such as id
 (e.g., <div [id]="userInput"> or <a id="ng-state">) before the genuine <script> tag is parsed by the
 browser, the attacker-controlled element takes precedence in the DOM lookup. During hydration, when
 Angular calls document.getElementById('ng-state'), the browser returns the attacker's clobbered element.
 Angular then attempts to parse the text content or attributes of this clobbered element as JSON. This
 vulnerability is fixed in 22.0.1, 21.2.17, and 20.3.25. (CVE-2026-54267)

Solution

Update the @angular/core library and its related packages to version 20.3.25 or later.
