CVE-2026-110181: PostgreSQL Anonymizer SQL-standard function body bypass

CVE-2026-110181 · Severity: medium · CVSS 6.5 · Published 2026-10-28

PostgreSQL Anonymizer is an extension that masks sensitive data in databases. A vulnerability allows users with temporary table creation privileges to bypass anonymization rules by exploiting a timing difference in how PostgreSQL parses function definitions. An attacker could read sensitive data that should have been masked.

Technologies: Dalibo PostgreSQL Anonymizer. Vendors: Dalibo.

Technical details

PostgreSQL Anonymizer checks SQL-standard function bodies at execution time, but PostgreSQL itself analyzes them at declaration time, creating a window for bypass. The vulnerability requires TEMPORARY privilege, a low-level permission that allows creation of temporary tables. An attacker can craft a function that exposes masked data during the analysis phase before Anonymizer's checks run.

Affected products

  • Dalibo PostgreSQL Anonymizer before 3.3.0
