NVD Description

Note: Versions mentioned in the description apply only to the upstream postgresql:15/postgresql-test-rpm-macros package and not the postgresql:15/postgresql-test-rpm-macros package as distributed by AlmaLinux. See How to fix? for AlmaLinux:9 relevant fixed versions and status.

A vulnerability was found in PostgreSQL with the use of the MERGE command, which fails to test new rows against row security policies defined for UPDATE and SELECT. If UPDATE and SELECT policies forbid some rows that INSERT policies do not forbid, a user could store such rows.
