CVE-2026-6479 PostgreSQL SSL/GSS init causes denial of service, via uncontrolled recursion
PublishedHighCVSS 7.5 EPSS 0.60%Uncontrolled recursion in PostgreSQL SSL and GSS negotiation allows an attacker able to connect to a PostgreSQL AF_UNIX socket to achieve sustained denial of service. If SSL and GSS are both disabled, an attacker can do the same via access to a PostgreSQL TCP socket. Versions bef...
