SCA: security update for @angular/service-worker (GHSA-qxh6-94w6-9r5p)

high Tenable Self-Hosted Container Security Plugin ID 443201

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, an information
 disclosure vulnerability exists in the @angular/service-worker package of the Angular framework. When the
 Service Worker fetches assets, it preserves metadata (such as headers) from the original request. However,
 on cross-origin redirects, the Service Worker fails to strip sensitive headers, violating the Fetch
 redirect algorithm. This allows a remote attacker to obtain sensitive credentials (e.g., Authorization
 tokens, Proxy-Authorization credentials, or session cookies) by triggering a cross-origin redirect to an
 untrusted external origin. This vulnerability is fixed in 22.0.1, 21.2.17, and 20.3.25. (CVE-2026-54264)

Solution

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