CVE-2021-29053Network attack vector

Authenticated SQL injection via classPKField

Published May 17, 2021 · Updated Jul 9, 2026

SQL injection in Liferay Portal 7.3.5 and Liferay DXP 7.3 before fix pack 1 allows remote authenticated users to execute arbitrary SQL. CommerceChannelRelFinder.countByC_C and findByC_C incorporate the attacker-controlled classPKField parameter into database queries without adequate neutralization. An authenticated account can therefore read or alter database data and interrupt service by executing SQL within the application's database privileges.
