CVE-2026-17346Network attack vector

SQL injection via unescaped database object names

Published Jul 31, 2026 · Updated Jul 31, 2026

SQL injection in pgAdmin 4 before 9.17 allows remote authenticated users to execute SQL through crafted database object names. Index Statistics and publication or subscription dependency templates insert pg_catalog names into quoted SQL literals without qtLiteral escaping. A low-privileged database role can plant an apostrophe-bearing name; opening the affected view executes stacked statements with the viewer's database privileges.
