H2O Vulnerable to Denial of Service (DoS) via `/3/ImportFiles` Endpoint
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 endpoint, eventually...
H2O Vulnerable to Denial of Service (DoS) via `HEAD` Request
A vulnerability in the typeahead endpoint of h2oai/h2o-3 version 3.46.0 allows for a denial of service. The endpoint performs a HEAD request to verify the existence of a specified resource without setting a timeout. An attacker can exploit this by sending multiple requests to an attacker-controll...
PYSEC-2026-1443 H2O Vulnerable to Denial of Service (DoS) via `/3/ImportFiles` Endpoint
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 endpoint, eventually...
H2O Vulnerable to Denial of Service (DoS) via Large GZIP Parsing
In h2oai/h2o-3 version 3.46.0.2, a vulnerability exists where uploading and repeatedly parsing a large GZIP file can cause a denial of service. The server becomes unresponsive due to memory exhaustion and a large number of concurrent slow-running jobs. This issue arises from the improper handling...
H2O Vulnerable to Arbitrary File Overwrite via File Export
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 target server with a...
PYSEC-2026-1436 H2O Vulnerable to Arbitrary File Overwrite via File Export
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 target server with a...
H2O Vulnerable to Execution of Arbitrary Files
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 possible for an attacke...
H2O Vulnerable to Denial of Service (DoS) and File Write
In h2oai/h2o-3 version 3.46.0.1, the runtool command exposes classes in the water.tools package through the ast parser. This includes the XGBoostLibExtractTool class, which can be exploited to shut down the server and write large files to arbitrary directories, leading to a denial of service...
H2O Vulnerable to Denial of Service (DoS) via `/3/ParseSetup` Endpoint
A vulnerability in the /3/ParseSetup endpoint of h2oai/h2o-3 version 3.46.0.1 allows for a denial of service DoS attack. The endpoint applies a user-specified regular expression to a user-controllable string. This can be exploited by an attacker to cause inefficient regular expression complexity,...
PYSEC-2026-352 H2O.ai H2O vulnerable to deserialization attacks via a JDBC Connection URL
H2O.ai H2O through 3.46.0.4 allows attackers to arbitrarily set the JDBC URL, leading to deserialization attacks, file reads, and command execution. Exploitation can occur when an attacker has access to post to the ImportSQLTable URI with a JSON document containing a connectionurl property with a...
PYSEC-2026-351 H2O Deserialization of Untrusted Data Vulnerability
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. The vulnerability exists in the endpoints POST /99/ImportSQLTable and POST /3/SaveToHiveTable, where user-controlled JDBC URLs are...
H2O 代码注入漏洞
H2O is an open-source memory platform for distributed, scalable machine learning developed by H2O.ai. Versions of H2O 3.46.0.9 and earlier contained a code injection vulnerability. This vulnerability stemmed from insufficient security controls in the parameter blacklist mechanism. Attackers could...
H2O has an External Control of File Name or Path vulnerability
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-2022-35894
An issue was discovered in Insyde InsydeH2O with kernel 5.0 through 5.5. The SMI handler for the FwBlockServiceSmm driver uses an untrusted pointer as the location to copy data to an attacker-specified buffer, leading to information disclosure...
