SCA: security update for @angular/platform-server (GHSA-45q2-gjvg-7973)

high Tenable Self-Hosted Container Security Plugin ID 440924

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 versions 19.2.21, 20.3.19, 21.2.9, and 22.0.0-next.8,
a Server-Side Request Forgery (SSRF) vulnerability exists in @angular/platform-server due to improper
handling of URLs during Server-Side Rendering (SSR). When an attacker sends a request such as GET
/\evil.com/ HTTP/1.1 the server engine (Express, etc.) passes the URL string to Angular’s rendering
functions. Because the URL parser normalizes the backslash to a forward slash for HTTP/HTTPS schemes, the
internal state of the application is hijacked to believe the current origin is evil.com. This
misinterpretation tricks the application into treating the attacker’s domain as the local origin.
Consequently, any relative HttpClient requests or PlatformLocation.hostname references are redirected to
the attacker controlled server, potentially exposing internal APIs or metadata services. This issue has
been patched in versions 19.2.21, 20.3.19, 21.2.9, and 22.0.0-next.8. (CVE-2026-41423)

Solution

Update the @angular/platform-server library and its related packages to version 19.2.21 or later.
