CVE-2026-105615— PostgreSQL Anonymizer: Masked roles can read the statistics of masked columns in pg_stats

Quick assessment

Affected

DALIBO PostgreSQL Anonymizer

Exploitation

No confirmed in-the-wild exploitation; assess based on exposure

Recommended action

Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

只要拥有对某张表的 SELECT 权限，PostgreSQL 中该表的优化统计信息就会可见。因此，一个被掩码的角色可以通过统计视图中的直方图和 MCVs（最常用值）读取部分受限数据。该漏洞已在 PostgreSQL Anonymizer 3.3.0 及更高版本中修复。

Vulnerability Title

PostgreSQL Anonymizer: Masked roles can read the statistics of masked columns in pg_stats

Source: CVE Program / CVE List V5

Vulnerability Description

PostgreSQL's optimized statistics on a table are visible as long as you have SELECT privilege on said table. A masked role can therefore read a limited subset of the data through the statistics view's histograms and mcvs. The vulnerability is resolved in PostgreSQL Anonymizer 3.3.0 and later versions.
