If an administrator has installed files of a vulnerable, trusted, non-bundled extension, an attacker with database-level CREATE privilege can execute arbitrary code as the bootstrap superuser.(CVE-2023-39417)

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.(CVE-2023-2455)

schema_element defeats protective search_path changes, It was found that certain database calls in PostgreSQL could permit an authed attacker with elevated database-level privileges to execute arbitrary code.(CVE-2023-2454)");
