CVE-2024-8019: PyTorch Lightning path traversal vulnerability

March 20, 2025 (updated March 21, 2025)

In lightning-ai/pytorch-lightning version 2.3.2, a vulnerability exists in the LightningApp when running on a Windows host. The vulnerability occurs at the /api/v1/upload_file/ endpoint, allowing an attacker to write or overwrite arbitrary files by providing a crafted filename. This can lead to potential remote code execution (RCE) by overwriting critical files or placing malicious files in sensitive locations.
