NVD Description

Note: Versions mentioned in the description apply only to the upstream postgresql-15 package and not the postgresql-15 package as distributed by Debian. See How to fix? for Debian:12 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.
