What is CVE-2026-105615?

A vulnerability in PostgreSQL Anonymizer allows users with SELECT privilege to access sensitive statistics on tables. Through this issue, a masked role may exploit the statistics view's histograms and most common values (mcvs), potentially revealing a limited subset of the underlying data. This raises serious concerns regarding data confidentiality and user privacy. The problem has been addressed in version 3.3.0, which implements stronger protections to prevent such unauthorized access.

Affected Version(s)
