NewCVE-2026-88056 (opens in a new tab)How to fix?
Upgrade @angular/platform-server to version 20.3.30, 21.2.22, 22.1.4 or higher.
Overview
@angular/platform-server is an Angular - library for using Angular in Node.js
Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) via the URL resolution process. An attacker can cause requests to be sent to an attacker-controlled origin and exfiltrate sensitive server-side credentials by submitting URLs containing leading Unicode whitespace characters that bypass application-level same-origin checks but are interpreted differently by the server-side URL resolution utility.
Workaround
This vulnerability can be mitigated by validating and sanitizing input URLs to disallow leading Unicode whitespace characters before performing origin checks or passing them to the HTTP client, and by avoiding sole reliance on origin checks that may be affected by whitespace normalization discrepancies.
