Description
PostgreSQL Anonymizer contains a vulnerability that allows unprivileged masked users to execute arbitrary code by abusing operators, domain casts, or view subqueries that carry untrusted expressions. When these objects are evaluated in the context of the extension’s masking mechanisms, the malicious code can run with elevated privileges. The issue is fixed in PostgreSQL Anonymizer 3.1.4 and later versions
