In versions 2.0.0 through 3.0.8, the ProxySQL MySQL frontend accepts the `PROXY UNKNOWN <addr> <addr> <port> <port>\\r\\n` PP1 frame as a well-formed PROXY protocol header. The HAProxy PROXY protocol v1 specification says that when the protocol token is `UNKNOWN`, the receiver MUST ignore any address fields that follow it, because the proxy has declared it cannot determine the client identity. ProxySQL parses those address fields "},"products":[{"@id":"cpe:2.3:a:sysown:proxysql:\\>\\=_2.0.0\\,_\\<_3.0.9:*:*:*:*:*:*:*","identifiers":{"cpe23":"cpe:2.3:a:sysown:proxysql:\\>\\=_2.0.0\\,_\\<_3.0.9:*:*:*:*:*:*:*"}}],"status":"affected","action_statement":"No fixed version is published yet; monitor the upstream advisory.","timestamp":"2026-06-19T19:28:46.248Z"}]}
