CVE-2026-110182: PostgreSQL Anonymizer information disclosure in partial() functions

CVE-2026-110182 · Severity: medium · CVSS 4.3 · Published 2026-10-28

PostgreSQL Anonymizer is an extension that masks sensitive data in databases. The anon.partial() and anon.partial_email() functions can inadvertently expose complete data when the underlying values are small, defeating the purpose of anonymization. This could allow an attacker to view full customer names, email addresses, or other personal information that should have been masked.

Technical details

The vulnerability exists in the anon.partial() and anon.partial_email() functions which fail to properly truncate data below a certain size threshold, revealing the complete original values instead of masked versions. An attacker with database read access can query these functions on small data values to recover sensitive information. The issue is fixed in version 3.3.0 and later.
