CVE-2026-8387 Detail

Description

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.
