CVE-2026-105615 (GCVE-0-2026-105615)

Vulnerability from cvelistv5 – Published: 2026-10-28 17:31 – Updated: 2026-10-28 17:31

Title

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

Summary

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.

Severity

3.5 (Low)
