CVE-2025-5690 | Cursor allows PostgreSQL Anonymizer masked user to gain unauthorized access to authentic data

PostgreSQL Anonymizer v2.0 and v2.1 contain a vulnerability that allows a masked user to bypass the masking rules defined on a table and read the original data using a database cursor or the --insert option of pg_dump. This problem occurs only when dynamic masking is enabled, which is not the default setting. The problem is resolved in version 2.2.1
