Exploitation can occur when an attacker has access to post to the ImportSQLTable URI with a JSON document containing a connection_url property with any typical JDBC Connection URL attack payload such as one that uses queryInterceptors.","categories":["Libraries & packages"],"product":"ai.h2o:h2o-core","vendor":"n/a","ecosystem":"maven","affected_ranges":[{"source":"GitHub Advisory
