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...

PYSEC-2026-1376 Flair allows arbitrary code execution

A vulnerability, which was classified as critical, was found in flairNLP flair 0.14.0. Affected is the function ClusteringModel of the file flair\models\clustering.py of the component Mode File Loader. The manipulation leads to code injection. It is possible to launch the attack remotely. The...

PYSEC-2026-1738 open-webui allows enumeration of file names and traversal of directories by observing the error messages

An information disclosure vulnerability exists in open-webui version 0.3.8. The vulnerability is related to the embedding model update feature under admin settings. When a user updates the model path, the system checks if the file exists and provides different error messages based on the existenc...
