Description Vladimir Vasilev 2026-09-07 11:31:58 UTC

Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

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
