CVE-2026-10052
Quay/config-tool: quay/config-tool: ssrf via unfiltered ldap and smtp config validation endpoints
Description
A flaw was found in the Quay config-tool's LDAP and SMTP validation functions. An attacker with config editor access can exploit these functions, which make outbound connections to user-supplied endpoints without proper IP or host filtering. This allows the attacker to perform internal network reconnaissance from the Quay pod's network position, potentially mapping the internal network infrastructure.
