Versions 2.0.18 through 3.0.8 have a pre-authentication heap memory corruption vulnerability in the MySQL and PostgreSQL protocol first-read paths. A remote unauthenticated client can declare an oversized first packet length, and ProxySQL passes that attacker-controlled length directly to `recv()` while writing into a fixed 32 KB input queue. Version 3.0.9 patches the issue."},"products":[{"@id":"cpe:2.3:a:sysown:proxysql:\\>\\=_2.0.18\\,_\\<_3.0.9:*:*:*:*:*:*:*","identifiers":{"cpe23":"cpe:2.3:a:sysown:proxysql:\\>\\=_2.0.18\\,_\\<_3.0.9:*:*:*:*:*:*:*"}}],"status":"affected","action_statement":"No fixed version is published yet; monitor the upstream advisory.","timestamp":"2026-06-19T19:27:12.183Z"}]}
