AI-analyzed exploit summary This repository contains a functional Python-based PoC for CVE-2026-42281, an unauthenticated SSRF vulnerability in MagicMirror² ≤ 2.35.0. The exploit leverages the `/cors` endpoint to perform internal network scans, cloud metadata exfiltration, and config extraction.

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.
