CVE-2025-66249

Estado: AnalizadaMedia (6.3)—

Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in Apache Livy.

This issue affects Apache Livy: from 0.3.0 before 0.9.0.

The vulnerability can only be exploited with non-default Apache Livy Server settings. If the configuration value "livy.file.local-dir-whitelist" is set to a non-default value, the directory checking can be bypassed.

Users are recommended to upgrade to version 0.9.0, which fixes the issue.
