MagicMirror是MagicMirror社区的一款可显示天气、日历等信息的智能镜子。 MagicMirror 2.37.0之前版本存在服务端请求伪造漏洞，该漏洞源于defaultmodules/calendar/node_helper.js中的ADD_CALENDAR处理器接受攻击者控制的URL、身份验证数据和selfSignedCert设置，导致服务端请求伪造（SSRF）问题，可能允许未经身份验证的攻击者通过/calendar命名空间泄露内部服务响应数据，或执行盲请求和计时探测。

Vulnerability Title
MagicMirror: ssrf calendar .js
Source: CVE Program / CVE List V5
Vulnerability Description
MagicMirror² is an open source modular smart mirror platform. Prior to 2.37.0, the ADD_CALENDAR handler in defaultmodules/calendar/node_helper.js accepts an attacker-controlled URL, authentication data, and selfSignedCert setting through the unauthenticated Socket.IO namespace /calendar. The handler passes these fields to CalendarFetcher, causing a server-side request without SSRF validation and optionally disabling TLS verification. When the response is valid iCal, CALENDAR_EVENTS returns parsed event data to the attacker, allowing internal-service response data to be exfiltrated; other responses still provide a blind request and timing primitive. This issue is fixed in version 2.37.0.
