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

Quick assessment

Affected
allegroai allegroai/clearml
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

allegroai clearml是allegroai公司开源的一个大模型流水线工具。 ClearML 1.16.5及之前版本存在路径遍历漏洞，该漏洞源于使用ZipFile.extractall()方法提取.zip压缩包时缺乏路径遍历验证，可能导致攻击者写入任意文件至文件系统，进而通过cron作业注入、SSH密钥覆盖或Web Shell部署等方式实现远程代码执行。

Vulnerability Title
Relative Path Traversal in allegroai/clearml
Source: CVE Program / CVE List V5
Vulnerability 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.
