@angular/ssr is vulnerable to Server-Side Request Forgery (SSRF)
46
Medium Risk
This Affects:
@angular/ssrTL;DR
Affected versions of this package are vulnerable to server-side request forgery (SSRF) because createRequestUrl uses new URL(originalUrl ?? url, base) and allows schema-relative paths (//host) to override the base. An attacker can craft a request path beginning with // (e.g. //attacker.com/path), causing Angular SSR to treat the request as coming from http://attacker.com and perform relative requests against attacker-controlled hosts. This enables SSRF, domain spoofing, and potential content injection.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range.
