Doc Text:
A flaw was found in MagicMirror². An unauthenticated remote attacker can exploit a Server-Side Request Forgery (SSRF) vulnerability, which allows a server to be tricked into making requests to an unintended location, in the /cors endpoint. This enables the attacker to force the MagicMirror² server to perform arbitrary HTTP requests to internal networks, cloud metadata services, and localhost services. This can lead to significant information disclosure, including server-side secrets, by expanding environment variable placeholders.

Description OSIDB Bzimport 2026-05-14 21:02:44 UTC
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.
