SCA: security update for @angular/service-worker (GHSA-95qp-cmmw-mgqv)

medium Tenable Cloud Security Plugin ID 443208

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 explicit client-defined safety parameters: the credentials configuration (such
 as credentials: 'omit') and the HTTP cache mode configuration (such as cache: 'no-store'). These are
 reverted back to standard browser-default parameters (credentials: 'same-origin' and default HTTP cache
 properties). This causes the browser to include active credentials (such as cookies or Authorization
 headers) on outbound requests where the client-side developer explicitly instructed they should be
 omitted, leading to potential session leaks. Additionally, it causes private or non-cacheable resources to
 be cached by the service worker's engine, making private page states accessible or persistent inside the
 client's local cache post-logout. This vulnerability is fixed in 22.0.0-rc.2, 21.2.15, 20.3.22, and
 19.2.23. (CVE-2026-50184)

Solution

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