CVE-2026-0603 Red Hat CVE debrief
A high-severity vulnerability, CVE-2026-0603, has been identified in Hibernate, a popular Java framework for building robust and scalable applications. This vulnerability, with a CVSS score of 8.3, allows remote attackers with low privileges to exploit a second-order SQL injection vulnerability. By providing specially crafted, unsanitized non-alphanumeric characters in the ID column when the InlineIdsOrClauseBuilder is used, attackers can lead to sensitive information disclosure, such as reading system files, and allow for data manipulation or deletion within the application's database, resulting in an application-level denial of service. The vulnerability was first disclosed on January 23, 2026, and has since been modified on June 30, 2026. Users of affected versions should apply patches or mitigations as soon as possible to prevent exploitation.
