Descriptions

Row security policies disregard user ID changes after inlining; PostgreSQL could permit incorrect policies to be applied in certain cases where role-specific policies are used and a given query is planned under one role and then executed under other roles. This scenario can happen under security definer functions or when a common user and query is planned initially and then re-used across multiple SET ROLEs. Applying an incorrect policy may permit a user to complete otherwise-forbidden reads and modifications. This affects only databases that have used CREATE POLICY to define a row security policy.

A flaw was found in PostgreSQL, which could permit incorrect policies being applied in certain cases where role-specific policies are used and a given query is planned under one role and executed under other roles. This scenario can happen under security definer functions, or when a common user and query is planned initially and then re-used across multiple SET ROLEs. Applying an incorrect policy may permit a user to complete otherwise forbidden reads and modifications. This only affects databases that have used CREATE POLICY to define a row security policy.

Alexander Lakhin discovered that PostgreSQL incorrectly handled certain CREATE privileges. An authenticated user could possibly use this issue to execute arbitrary code as the bootstrap supervisor. Wolfgang Walther discovered that PostgreSQL incorrectly handled certain row security policies. An authenticated user could possibly use this issue to complete otherwise forbidden reads and modifications.
