What is CVE-2024-2338?

PostgreSQL Anonymizer v1.2 contains a SQL injection vulnerability that can be exploited by users who own a table when dynamic masking is enabled. This flaw arises from the improper handling of complex expressions provided as masking values, which can be exploited to create masked views that inadvertently allow SQL injection. As a result, an attacker could elevate their privileges to superuser status if dynamic masking is in use. Users without table ownership, particularly masked users, do not have the ability to exploit this vulnerability. The issue has been addressed in version 1.3.
