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...
PYSEC-2026-1439 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...
PYSEC-2026-1437 h2o vulnerable to unexpected POST request shutting down server
In h2oai/h2o-3 version 3.46.0, the runtool command in the rapids component allows the main function of any class under the water.tools namespace to be called. One such class, MojoConvertTool, crashes the server when invoked with an invalid argument, causing a denial of service...
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...
