A decade-old privilege-escalation bug in PostgreSQL's logical decoding lets replication-privileged accounts run OS-level code — patch now, especially in CDC-heavy architectures.
Summary written by editorial AI · Source link below
PostgreSQL has released updates to address a security flaw that allows an account with the REPLICATION attribute to run arbitrary code as the operating-system user running the database server.
The flaw, tracked as CVE-2026-6471 (CVSS score: 7.2), has been present since logical decoding was introduced in PostgreSQL 9.4 in 2014. Versions before PostgreSQL 18.6, 17.11, 16.15, 15.19, and 14.24 are
Editorial Analysis
Framed for the SOC Analyst desk

Audit all PostgreSQL instances for accounts with the REPLICATION attribute and apply the latest patch immediately.
A long-standing PostgreSQL flaw could let an attacker with database replication access take full control of the underlying server.
