CVE-2025-15031: A vulnerability in MLflow's pyfunc extraction process allows for arbitrary file writes due to improper handling of tar a

MLflow, a machine learning platform, has a vulnerability (CVE-2025-15031) in how it extracts model files from compressed archives. The issue is that the software uses `tarfile.extractall` (a Python function that unpacks compressed tar files) without checking whether file paths are safe, allowing attackers to use specially crafted archives with `..` (parent directory references) or absolute paths to write files outside the intended folder. This could let attackers overwrite files or execute malicious code, especially in shared environments or when processing untrusted model files.
