CVE-2023-2454: Input Validation

First published: Fri May 12 2023(Updated: )

CVE-2023-2454: CREATE SCHEMA ... schema_element defeats protective search_path changes. Versions Affected: 11 - 15. This problem is quite old. This enabled an attacker having database-level CREATE privilege to execute arbitrary code as the bootstrap superuser. Database owners have that right by default, and explicit grants may extend it to other users. <a href="https://www.postgresql.org/support/security/CVE-2023-2454/">https://www.postgresql.org/support/security/CVE-2023-2454/</a>
