CVE-2026-30637Public exploitNetwork attack vector

Unauthenticated internal data disclosure via unfiltered URL fetch

Published Mar 27, 2026 · Updated Mar 27, 2026

SSRF in OTCMS 7.66 and earlier allows remote attackers to read local files and internal-service responses through /admin/read.php. AnnounContent passes the unauthenticated url query parameter to ReqUrl::UseAuto, whose default path issues the request with cURL or fallback transports without destination filtering. A remotely reachable installation is sufficient; the server returns fetched content, exposing files and network-only service data.
