SCA: security update for @angular/common (GHSA-p297-fm68-3q8c)

medium Tenable Cloud Security Plugin ID 447932

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 20.3.28, 21.2.20, and 22.1.1, Angular's
@angular/common HttpTransferCache can cache an authenticated response when Server-Side Rendering (SSR) and
hydration use a hierarchical HttpClient configured with withRequestsMadeViaParent. The child TransferCache
evaluates an initially anonymous request before delegation, then a parent withInterceptors chain adds an
Authorization header, cookie, or API token; although the parent cache skips the authenticated request, the
child still stores the private response in TransferState serialized as JSON in the ng-state script.
Exploitation requires provideClientHydration, child provideHttpClient delegation through
withRequestsMadeViaParent, parent-level credential injection, and an SSR HTML response shared across users
by a CDN, reverse proxy, or application cache. A later unauthenticated or unauthorized visitor can receive
the cached HTML containing the earlier authenticated user's sensitive response data. Applications can
mitigate by attaching credentials at the child, filtering sensitive endpoints with
withHttpTransferCacheOptions, disabling transfer caching for sensitive routes, or marking personalized
HTML private or no-store. This issue is fixed in versions 20.3.28, 21.2.20, and 22.1.1. (CVE-2026-88059)

Solution

Update the @angular/common library and its related packages to version 20.3.28 or later.
