Summary
A vulnerability in allegroai/clearml versions up to 1.16.5 allows relative path traversal when extracting .zip archives using ZipFile.extractall() in StorageManager._extract_to_cache(). Lack of path validation enables arbitrary file writes.
Risk Assessment
The risk includes remote code execution via cron job injection, SSH key overwrite, or web shell deployment, potentially leading to full system compromise.
Recommendation
Immediately update allegroai/clearml to version 2.1.6 or later, which fixes this vulnerability.
Original NVD description (English source)
A vulnerability in allegroai/clearml versions up to and including 1.16.5 allows for relative path traversal when extracting `.zip` archives using the `ZipFile.extractall()` method in `StorageManager._extract_to_cache()`. This issue arises due to the lack of path traversal validation, enabling an attacker to write arbitrary files to the filesystem. Attack vectors include dataset downloads, artifact downloads, model downloads, and offline session imports. The vulnerability can lead to remote code execution through methods such as cron job injection, SSH key overwrite, or web shell deployment. The issue is resolved in version 2.1.6.
