CVE-2025-8406
MEDIUM6.3EPSS 0.04%ZenML is vulnerable to Path Traversal through its `PathMaterializer` class
Published: 10/5/2025Modified: 10/7/2025
Description
ZenML version 0.83.1 is affected by a path traversal vulnerability in the `PathMaterializer` class. The `load` function uses `is_path_within_directory` to validate files during `data.tar.gz` extraction, which fails to effectively detect symbolic and hard links. This vulnerability can lead to arbitrary file writes, potentially resulting in arbitrary command execution if critical files are overwritten.
