CVE-2026-42281
MagicMirror²: Unauthenticated SSRF via /cors endpoint
Description
MagicMirror² is an open source modular smart mirror platform. Prior to 2.36.0, an unauthenticated Server-Side Request Forgery (SSRF) vulnerability in the /cors endpoint allows any remote attacker to force the MagicMirror² server to perform arbitrary HTTP requests to internal networks, cloud metadata services, and localhost services. The endpoint also expands environment variable placeholders (**VAR_NAME**), enabling exfiltration of server-side secrets. This vulnerability is fixed in 2.36.0.

Action Type Old Value New Value Added Translation Title: MagicMirror de MagicMirrorOrg, Description: MagicMirror² es una plataforma de espejo inteligente modular de código abierto. Antes de la versión 2.36.0, una vulnerabilidad de falsificación de petición del lado del servidor (SSRF) no autenticada en el endpoint /cors permite a cualquier atacante remoto forzar al servidor MagicMirror² a realizar peticiones HTTP arbitrarias a redes internas, servicios de metadatos en la nube y servicios de localhost. El endpoint también expande marcadores de posición de variables de entorno (VAR_NAME), lo que permite la exfiltración de secretos del lado del servidor. Esta vulnerabilidad está corregida en la versión 2.36.0. -
