Quick assessment

Affected
cohere-ai cohere-python
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.

Cohere Python SDK 5.11.0 至 7.2.0 版本中存在一个路径遍历（tar slip）漏洞，位于 _s3_models_dir_to_tarfile 函数中，该漏洞允许通过未经验证的 tarfile.extractall 调用进行任意文件写入。攻击者若能够将模型归档文件写入受害者的 S3 前缀，便可以在归档中包含绝对路径或包含 ../ 的条目，从而覆盖 SDK 主机上的文件。
