| CVE-2026-3960 | Cri | 9.8 | < 3.46.0.10 | 3.46.0.10 | 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 JDB | |
| CVE-2024-5986 | Cri | 9.1 | <= 3.46.0.1 | — | 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 `/ | |
| CVE-2025-6544 | — | <= 3.46.0.7 | — | Sep 21, 2025 | A deserialization vulnerability exists in h2oai/h2o-3 versions <= 3.46.0.8, allowing attackers to read arbitrary system files and execute arbitrary code. The vulnerability arises from improper handling of JDBC connection parameters, which can be exploited by bypassing regular exp | ||
| CVE-2024-10549 | — | >= 3.30.0.7, <= 3.46.0.1 | — | Mar 20, 2025 | A vulnerability in the `/3/Parse` endpoint of h2oai/h2o-3 version 3.46.0.1 allows for a denial of service (DoS) attack. The endpoint uses a user-specified string to construct a regular expression, which is then applied to another user-specified string. By sending multiple simulta | ||
| CVE-2024-8062 | — | >= 3.2.0.1, <= 3.46.0 | — | Mar 20, 2025 | A vulnerability in the typeahead endpoint of h2oai/h2o-3 version 3.46.0 allows for a denial of service.

| CVE-2024-7768 | — | <= 3.46.1 | — | Mar 20, 2025 | A vulnerability in the `/3/ImportFiles` endpoint of h2oai/h2o-3 version 3.46.1 allows an attacker to cause a denial of service. The endpoint takes a single GET parameter, `path`, which can be recursively set to reference itself. This leads the server to repeatedly call its own en | ||
| CVE-2024-6863 | — | >= 3.32.1.2, <= 3.46.0 | — | Mar 20, 2025 | In h2oai/h2o-3 version 3.46.0, an endpoint exposing a custom EncryptionTool allows an attacker to encrypt any files on the target server with a key of their choosing. The chosen key can also be overwritten, resulting in ransomware-like behavior. This vulnerability makes it possib | ||
| CVE-2024-8616 | — | >= 3.10.4.1, <= 3.46.0 | — | Mar 20, 2025 | In h2oai/h2o-3 version 3.46.0, the `/99/Models/{name}/json` endpoint allows for arbitrary file overwrite on the target server.

| CVE-2024-6854 | — | >= 3.32.1.1, <= 3.46.0 | — | Mar 20, 2025 | In h2oai/h2o-3 version 3.46.0, the endpoint for exporting models does not restrict the export location, allowing an attacker to export a model to any file in the server's file structure, thereby overwriting it. This vulnerability can be exploited to overwrite any file on the targ | ||
| CVE-2024-10553 | — | < 3.46.0.6 | 3.46.0.6 | Mar 20, 2025 | A vulnerability in the h2oai/h2o-3 REST API versions 3.46.0.4 allows unauthenticated remote attackers to execute arbitrary code via deserialization of untrusted data.
