CERT-FR has published an advisory regarding a privilege escalation vulnerability affecting PostgreSQL Anonymizer versions prior to 3.1. The flaw, tracked as CVE-2026-9617, enables an attacker to elevate their privileges within affected systems.

PostgreSQL Anonymizer is an extension that provides data masking and anonymization capabilities for PostgreSQL databases. The vulnerability represents a significant security risk for organizations using older versions of the extension, as privilege escalation flaws can allow attackers to gain unauthorized administrative access to database systems.
