Angular < 19.2.21 Server-Side Request Forgery

high Web App Scanning Plugin ID 115616

Synopsis

Angular < 19.2.21 Server-Side Request Forgery

Description

According to its self-reported version number, Angular is prior to 19.0.0, 19.x prior to 19.2.21, 20.x prior to 20.3.19 or 21.x prior to 21.2.9. It is, therefore, affected by a Server-Side Request Forgery (SSRF) vulnerability in @angular/platform-server. Protocol-relative and backslash request URLs (such as /\evil.com/) cause the SSR engine to treat the attacker domain as the current origin, redirecting relative HttpClient requests to an attacker-controlled server. (CVE-2026-41423)

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Angular version 19.2.21 or later.
