CVE-2025-10279 (GCVE-0-2025-10279)

Vulnerability from cvelistv5 – Published: 2026-02-02 10:36 – Updated: 2026-02-02 17:48

Title

Privilege Escalation in mlflow/mlflow

Summary

In mlflow version 2.20.3, the temporary directory used for creating Python virtual environments is assigned insecure world-writable permissions (0o777). This vulnerability allows an attacker with write access to the `/tmp` directory to exploit a race condition and overwrite `.py` files in the virtual environment, leading to arbitrary code execution. The issue is resolved in version 3.4.0.

Summary

Privilege Escalation in mlflow/mlflow

Details

In mlflow version 2.20.3, the temporary directory used for creating Python virtual environments is assigned insecure world-writable permissions (0o777). This vulnerability allows an attacker with write access to the /tmp directory to exploit a race condition and overwrite .py files in the virtual environment, leading to arbitrary code execution. The issue is resolved in version 3.4.0.
