Last modified

CVE-2025-8406 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. 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. EPSS estimates a 0.33% chance of exploitation in the next 30 days.

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.
