Server shutdown and file writes via exposed classes
Published Mar 20, 2025 · Updated Oct 15, 2025
Code injection in H2O.ai H2O-3 3.46.0.1 allows remote attackers to write files and shut down the server through run_tool. The AST parser lets run_tool invoke main methods on classes in water.tools, and XGBoostLibExtractTool accepts an attacker-chosen directory for native-library extraction. No privileges or user interaction are required; invoking the exposed class can fill arbitrary directories with large files or terminate the H2O-3 process.

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.
