Vulnerability Title
Spring Boot Admin Server < 4.1.2 SSRF via Unauthenticated Instance Registration
Source: CVE Program / CVE List V5
Vulnerability Description
Spring Boot Admin Server before 4.1.2 contains a server-side request forgery vulnerability that allows unauthenticated attackers to register instances with attacker-controlled healthUrl and managementUrl parameters without validation against private IP ranges or metadata endpoints. Attackers can force the server to make HTTP requests to arbitrary internal addresses and retrieve response bodies via the actuator proxy to exfiltrate cloud credentials.
