CVE-2026-105615

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

Published Oct 28, 2026 CVSS 3.1 · 3.5 Low EPSS < 1% KEV · Not listed
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.

Remediation

Vendor Workaround

For sensitive columns, statitics can be disabled with `ALTER TABLE my_table ALTER COLUMN my_col SET STATISTICS 0; ANALYZE my_table;`.
