scalar/astro v0.1.13 was discovered to contain a Server-Side Request Forgery (SSRF) in the scalar_url query parameter of the Scalar Proxy endpoint. This vulnerability allows unauthenticated attackers to force the backend server to send HTTP requests to attacker-controlled URLs, leading to authentication cookies and headers exposure and possible privilege escalation.
