Angular SSR bug allows hostname hijacking, opening SSRF risk

The article discusses a security vulnerability in Angular related to hostname hijacking through server-side rendering. This flaw, with a CVSS score of 8.8, allows attackers to manipulate internal URLs to redirect requests, potentially exposing sensitive data via Server-Side Request Forgery (SSRF). The vulnerability lies in the `@angular/platform-server` package. To mitigate this risk, the Angular development team released an update that includes an allowlist mechanism for trusted domains.

Developers are advised to update their systems immediately to versions 21.2.13 or later, with temporary workarounds suggested if immediate updates are not feasible.
