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.
