CVE-2025-8406
Path Traversal in zenml-io/zenml
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.
