PostgreSQL Fixes 12-Year-Old Logical Decoding Flaw Enabling Replication-Role Code Execution
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
Many European enterprises use PostgreSQL as their primary RDBMS; any replication-enabled environment is exposed to OS-level compromise until patched.
Inventory all PostgreSQL deployments, revoke unnecessary REPLICATION attributes, and apply the security update within your emergency patch window.
A long-standing PostgreSQL flaw could let an attacker with database replication access take full control of the underlying server.
