Remote code execution via unrestricted Java method calls
Published Oct 6, 2022 · Updated Apr 21, 2025
Unsafe reflection in HSQLDB before 2.7.1 allows remote authenticated users to execute code via untrusted SQL statements. The SQL/JRT routine resolver accepts attacker-selected class and method names and makes static methods from any class on the application classpath callable by default. Exploitation requires an application to pass attacker-controlled SQL through Statement or PreparedStatement and, under the CNA assessment, low privileges and user interaction; successful calls execute with the database JVM's permissions.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
