CVE-2026-19634Public exploitNetwork attack vector

Superuser SQL execution via unescaped JSON object names

Published Sep 6, 2026 · Updated Sep 9, 2026

SQL injection in PostgreSQL Anonymizer before 3.1.4 allows context-dependent attackers to execute SQL through imported JSON object names. The to_seclabel() routine inserts JSON-derived schema, role, function, table, view, and column names into one-line SQL without identifier escaping, so a trailing comment discards the remaining statement. A superuser must import the attacker-influenced rules; injected statements then run with that superuser's database privileges.
