CVE-2026-8387
Relative Path Traversal in allegroai/clearml
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.
