    Title
    Cohere Python SDK 5.11.0 through 7.2.0 Path Traversal via SageMaker Tar Extraction
    Summary
    Cohere Python SDK 5.11.0 through 7.2.0 contains a path traversal (tar slip) vulnerability in _s3_models_dir_to_tarfile that allows arbitrary file write via unvalidated tarfile.extractall calls. Attackers who can write model archives to the victim's S3 prefix can include absolute paths or ../ members to overwrite files on the SDK host.
