| CVE-2025-6507 | Cri | 0.64 | 9.8 | 0.00 | Sep 1, 2025 | A vulnerability in the h2oai/h2o-3 repository allows attackers to exploit deserialization of untrusted data, potentially leading to arbitrary code execution and reading of system files. This issue affects the latest master branch version 3.47.0.99999. The vulnerability arises from the ability to bypass regular expression filters intended to prevent malicious parameter injection in JDBC connections. Attackers can manipulate spaces between parameters to evade detection, allowing for unauthorized file access and code execution. The vulnerability is addressed in version 3.46.0.8. | |
| CVE-2024-5986 | Cri | 0.59 | 9.1 | 0.00 | Feb 2, 2026 | A vulnerability in h2oai/h2o-3 version 3.46.0.1 allows remote attackers to write arbitrary data to any file on the server. This is achieved by exploiting the `/3/Parse` endpoint to inject attacker-controlled data as the header of an empty file, which is then exported using the `/3/Frames/framename/export` endpoint. The impact of this vulnerability includes the potential for remote code execution and complete access to the system running h2o-3, as attackers can overwrite critical files such as private SSH keys or script files. | |
| CVE-2025-5662 | Cri | 0.57 | 9.8 | 0.02 | Sep 2, 2025 | A deserialization vulnerability exists in the H2O-3 REST API (POST /99/ImportSQLTable) that affects all versions up to 3.46.0.7. This vulnerability allows remote code execution (RCE) due to improper validation of JDBC connection parameters when using a Key-Value format. The vulnerability is present in the MySQL JDBC Driver version 8.0.19 and JDK version 8u112. The issue is resolved in version 3.46.0.8. | |
| CVE-2025-10769 | Med | 0.41 | 6.3 | 0.00 | Sep 21, 2025 | A vulnerability has been found in h2oai h2o-3 up to 3.46.08. This affects an unknown function of the file /99/ImportSQLTable of the component H2 JDBC Driver. Such manipulation of the argument connection_url leads to deserialization. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way. | |
| CVE-2025-10768 | Med | 0.41 | 6.3 | 0.00 | Sep 21, 2025 | A flaw has been found in h2oai h2o-3 up to 3.46.08. The impacted element is an unknown function of the file /99/ImportSQLTable of the component IBMDB2 JDBC Driver. This manipulation of the argument connection_url causes deserialization. The attack may be initiated remotely. The exploit has been published and may be used. The vendor was contacted early about this disclosure but did not respond in any way. | |
| CVE-2026-3960 | Med | 0.31 | 5.9 | 0.00 | Apr 23, 2026 | A critical remote code execution vulnerability exists in the unauthenticated REST API endpoint /99/ImportSQLTable in H2O-3 version 3.46.0.9 and prior. The vulnerability arises due to insufficient security controls in the parameter blacklist mechanism, which only targets MySQL JDBC driver-specific dangerous parameters. An attacker can bypass these controls by switching the JDBC URL protocol to jdbc:postgresql: and exploiting PostgreSQL JDBC driver-specific parameters such as socketFactory and socketFactoryArg. This allows unauthenticated attackers to execute arbitrary code on the H2O-3 server with the privileges of the H2O-3 process. The issue is resolved in version 3.46.0.10. |
