SCA: security update for @angular/ssr (GHSA-7g7c-h8rr-7p6q)

medium Tenable Cloud Security Plugin ID 473014

Description

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

 - The Angular SSR is a server-rise rendering tool for Angular applications. Prior to versions 20.3.36,
 21.2.23, and 22.1.7, the CommonEngine retrieveSSGPage prerendered-page retrieval logic in
 @angular/ssr/node, and in @angular/ssr for versions 17 through 18, accepts a relative request URL
 containing a backslash parent-traversal segment on Windows. The non-special resolve:// URL base preserves
 the backslash, path.join interprets it as a Windows separator, and the
 pagePath.startsWith(normalize(publicPath)) check incorrectly accepts a sibling output directory whose name
 shares the configured public-directory prefix. An unauthenticated requester can therefore retrieve a
 sibling prerendered HTML page when that page contains the Angular SSG marker. The issue is limited to
 Windows deployments that pass relative request URLs to CommonEngine.render, have a prefix-sharing sibling
 output directory, and contain qualifying prerendered Angular HTML; it does not provide arbitrary file
 read. This issue is fixed in versions 20.3.36, 21.2.23, and 22.1.7. (CVE-2026-104871)

Solution

Update the @angular/ssr library and its related packages to version 20.3.36 or later.
