CVE-2026-6469

Name of the Vulnerable Software and Affected Versions PostgreSQL versions prior to 18.5 PostgreSQL versions prior to 17.11 PostgreSQL versions prior to 16.15 PostgreSQL versions prior to 15.19 PostgreSQL versions prior to 14.24

Description An incorrect ownership assignment occurs during the execution of the ALTER TABLE ALTER TYPE command. This issue reassigns ownership of dependent statistics objects to the current user, which improperly allows the table owner to execute DROP STATISTICS and ALTER STATISTICS commands while denying these actions to the previous owner of the statistics object. This flaw in access control could potentially allow a remote attacker to gain unauthorized access to delete or modify data.

Recommendations Update to version 18.5 or later. Update to version 17.11 or later. Update to version 16.15 or later. Update to version 15.19 or later. Update to version 14.24 or later.
