SCA: security update for @angular/service-worker (GHSA-gv2q-mqqv-365m)

medium Tenable Self-Hosted Container Security Plugin ID 443212

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 22.0.0-rc.2, 21.2.15 20.3.22, and 19.2.23, an issue in
the @angular/service-worker package compromises the integrity of request-policy enforcement during request
reconstruction. When the Angular Service Worker intercepts network requests for matched assets, it
reconstructs a new Request object using an internal helper function. During this reconstruction process,
the helper function strips the strict, client-defined request redirect policy configuration (such as
redirect: 'error'), falling back to the browser's default 'follow' strategy. If the target web application
makes client-side requests with a strict policy (e.g., expecting a network error instead of automatically
following redirects), the service worker will bypass this instruction and automatically follow HTTP 3xx
redirects to other destinations. This acts as an unintended proxy/intermediary ("Confused Deputy") and can
result in cookie/credential exposure or same-origin session-restricted data leakage if public dynamic
routes redirect to sensitive routes. This vulnerability is fixed in 22.0.0-rc.2, 21.2.15, 20.3.22, and
19.2.23. (CVE-2026-50169)

Solution

Update the @angular/service-worker library and its related packages to version 19.2.23 or later.
