PostgreSQL could allow unintended access to the database.
It was discovered that PostgreSQL incorrectly performed authorization

remote attacker could possibly use this issue to drop any function,
procedure, materialized view, index, or trigger under certain conditions.
The problem can be corrected by updating your system to the following package versions:
This update uses a new upstream release, which includes additional bug
fixes. After a standard system update you need to restart PostgreSQL to
make all the necessary changes.
