CVE-2025-12819Network attack vector

Unauthenticated SQL execution via malicious search path

Published Dec 3, 2025 · Updated Dec 27, 2025

SQL injection in PgBouncer before 1.25.1 allows remote attackers to execute arbitrary SQL during authentication through a crafted StartupMessage. The auth_query connection handler applied a client-controlled search_path to its backend connection before executing the authentication query. Exploitation requires search_path tracking, a nonempty auth_user, and an auth_query containing names that are not fully schema-qualified.
