The record

**Description** An Improper Neutralization of Special Elements Used in a Template Engine (CWE-1336) vulnerability in Jdbi allows arbitrary command execution when an application using `jdbi3-freemarker` permits attacker-influenced text to reach `FreemarkerEngine.parse()` as template source. This affects `org.jdbi:jdbi3-freemarker` through version 3.52.1. The developer opts into FreeMarker-backed SQL templating, but does not explicitly opt into reflective Java class loading from template source. Jdbi’s FreeMarker integration should not expose unrestricted Java class instantiation by default in a SQL templating module. While the SQL injection risk is acknowledged, Jdbi’s documentation explicitly supports and demonstrates dynamic SQL templating through defined attributes, including substitution of non-bindable SQL elements such `ORDER BY` columns.
