12-Year-Old PostgreSQL Vulnerability Enables Database, Server Takeover
CVE-2026-6471, a 12-year-old PostgreSQL vulnerability tracked as PostGREShell, allows attackers with low-level replication access to achieve remote code execution and gain persistent superuser privileges. The flaw enables complete database and server takeover through establishment of a durable backdoor.
Why it matters: PostgreSQL administrators and organizations running affected instances must audit replication access controls and apply patches immediately, as any account with replication privileges can compromise the entire database and underlying server.
