A flaw was found in PostgreSQL. This vulnerability allows incorrect row-level security policies to be applied via subqueries, WITH queries, security invoker views, or SQL-language functions that reference tables with row-level security policies. This issue arises when a query is planned under one role and executed under another, potentially leading to unauthorized reads or modifications of data.

A flaw was found in PostgreSQL. This vulnerability allows a less-privileged application user to view or change unintended rows using SET ROLE, SET SESSION AUTHORIZATION, or equivalent features resulting in loss of confidentiality integrity and availability.

A flaw was found in PostgreSQL PL/Perl. This vulnerability allows an unprivileged database user to change sensitive process environment variables (e.g., PATH) via incorrect control of environment variables.
