CVE-2026-10052Network attack vector

Authenticated SSRF via unfiltered validation endpoints

Published May 29, 2026 · Updated May 29, 2026

SSRF in Red Hat Quay 3 config-tool allows remote authenticated users to probe internal hosts through LDAP and SMTP validation. The LDAP and SMTP validation functions open connections to user-supplied endpoints without filtering private IP addresses or internal hostnames. Configuration-editor access is required, and successful requests expose reachable internal services from the Quay pod's network position.
