NVD Description

Note: Versions mentioned in the description apply only to the upstream postgresql:12/postgresql-contrib package and not the postgresql:12/postgresql-contrib package as distributed by AlmaLinux. See How to fix? for AlmaLinux:8 relevant fixed versions and status.

Missing authorization in PostgreSQL logical decoding allows a non-superuser holding REPLICATION privilege to dlopen any file visible to the operating system account running the server, via the choice of logical decoding plugin. This in turn runs arbitrary code as that account. Versions before PostgreSQL 18.6, 17.11, 16.15, 15.19, and 14.24 are affected.
