CVE-2026-27739: Angular SSR Request Vulnerability Enabling Server-Side Request Forgery
A critical vulnerability has been discovered in Angular Server-Side Rendering (SSR) that could allow attackers to manipulate request handling and trigger unauthorized server-side requests.

In affected versions, these headers were not strictly validated before being used to build request URLs.
