CVE-2026-48773
ProxySQL pre-auth heap overflow in MySQL and PostgreSQL first-packet handling
Sévérité par source
Le label propre à Trivy est CRITICAL. Critique selon Bitnami.
Description
ProxySQL is a proxy for MySQL and its forks, as well as PostgreSQL. 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.
