Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Apache Calcite Avatica JDBC driver (avatica-core, Maven) versions before 1.22.0 are vulnerable. The driver instantiates HTTP client classes named in the httpclient_impl connection property without checking that they implement the expected interface. An attacker who can control JDBC connection parameters and has a suitable class on the classpath could run arbitrary code, and in rare cases execute code remotely. Upgrade to avatica-core 1.22.0 or later.
