How the CVE Works
The Python-Future module (v1.0.0) automatically imports `test.py` if present in the working directory or sys.path. This unintended behavior occurs due to insecure default import mechanisms. An attacker can place a malicious `test.py` file in a directory where Python-Future is executed, leading to arbitrary code execution with the privileges of the Python process. The module fails to validate imports, enabling this unsafe loading of user-controlled scripts.
DailyCVE Form
Platform: Python-Future
Version: 1.0.0
Vulnerability: Arbitrary Code Execution
Severity: High
Date: Aug 14, 2025
Prediction: Patch by Sep 2025
What Undercode Say
pip show python-future grep -r "import test.py" /path/to/module python3 -c "import future; print(future.<strong>file</strong>)"
How Exploit
1. Attacker writes `test.py`
2. Places in target dir
3. Triggers Python-Future import
4. Code executes
