CVE-2026-13316

Cloud metadata disclosure via unvalidated proxy test URL

Published Jun 30, 2026 · Updated Jun 30, 2026

SSRF in Foreman HTTP proxy testing in Red Hat Satellite 6 allows local users with administrative privileges to read cloud instance metadata. The http_proxies_controller and http_proxy code accept modified test_url parameters and issue server-side HTTP requests without restricting cloud metadata addresses. Administrative access to the proxy test function is required, and successful requests expose AWS, GCP, or Azure instance metadata without changing data or interrupting service.
