Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The h2o package and the h2o-ext-xgboost package (versions 3.34.0.1 through 3.46.0.1) expose the run_tool command to classes in water.tools, including XGBoostLibExtractTool. The source gives few details on the access required, but the flaw can be used to shut down the server or write large files to arbitrary directories. No fixed version is listed.
