CVE 描述
Ech0 is an open-source, self-hosted publishing platform for personal idea sharing. Prior to 4.2.8, the GET /api/website/title endpoint accepts an arbitrary URL via the website_url query parameter and makes a server-side HTTP request to it without any validation of the target host or IP address. The endpoint requires no authentication. An attacker can use this to reach internal network services, cloud metadata endpoints (169.254.169.254), and localhost-bound services, with partial response data exfiltrated via the HTML tag extraction This vulnerability is fixed in 4.2.8. </div>

All the subjects and objects under the jurisdiction of a single security authority are considered to be under one security scope. If a vulnerability in a vulnerable component can affect a component which is in a different security scope than the vulnerable component, a Scope change occurs. Intuitively, whenever the impact of a vulnerability breaches a security/trust boundary and impacts components outside the security scope in which vulnerable component resides, a Scope change occurs.</p><div style='display:flex;padding-left:10px;'><div style='width:70px;'><p class='text-center bg-gray-800 text-gray-100 rounded'>Changed</p></div><div style='flex: 1;margin-left:5px;'><p>An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component.
