What is CVE-2026-2361?

PostgreSQL Anonymizer has a privilege escalation vulnerability that allows users with the CREATE privilege to execute malicious code, potentially granting them superuser privileges. This issue arises when users create a temporary view leveraging the anon.get_tablesample_ratio function. Instances with default CREATE permissions, particularly PostgreSQL 14 or those upgraded from older versions, face increased risks. The vulnerability has been addressed in versions 3.0.1 and later, emphasizing the importance of upgrading to secure environments.
