CVE-2026-10690 LOW 2.1

Server-Side Request Forgery in wonderwhy-er DesktopCommanderMCP 0.2.37 allows low-privileged remote MCP clients to coerce the server into fetching arbitrary internal URLs via the `url` argument of the `readFileFromUrl` function in `src/tools/filesystem.ts`. The unpatched server performs no origin validation and follows HTTP redirects automatically, enabling attackers to reach RFC 1918 private networks and cloud instance metadata services (AWS/GCP/Azure at 169.254.169.254) from the server's network context. Publicly available exploit code exists (CVSS 4.0 E:P), though no CISA KEV listing is present at time of analysis.
