Description Patrick Del Bello 2026-09-23 23:49:44 UTC 
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

A flaw was found in Hibernate ORM. This vulnerability allows an authenticated attacker to inject arbitrary SQL commands into the underlying database by manipulating the JSON path argument. The issue arises from improper handling of JSON path segments in the JsonPathHelper.appendInlinedJsonPathIncludingPassingClause() method, specifically when using Oracle, DB2, or HANA database dialects. Successful exploitation can lead to authorization bypass and significant data exfiltration, enabling the attacker to access sensitive information from the database.
