CVE-2026-10584Network attack vector

Sensitive-data interception via silent HTTP fallback

Published Jun 2, 2026 · Updated Jun 2, 2026

Cleartext transmission in the Graph Explorer proxy server before 3.0.1 allows remote attackers to intercept sensitive traffic over HTTP. When PROXY_SERVER_HTTPS_CONNECTION is true, the server accepts missing certificate files and silently starts over HTTP instead of rejecting the configuration. Exposure requires certificate generation or discovery to fail, typically under non-default configuration; standard deployments with HOST set are unlikely to be affected.
