## Overview

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.

## Affected

- `quay/quay-rhel8 (all versions)`
- `quay/quay-rhel9 (all versions)`

## Remediation
