MagicMirror vulnerable to unauthenticated SSRF via /cors endpoint
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.
