kagglehub is vulnerable to Path Traversal
53
Medium Risk
This Affects:
kagglehubTL;DR
kagglehub downloads model and dataset archives and unpacks them in _extract_archive inside http_resolver.py. For tar archives the library calls extractall without an extraction filter, so member paths and symlinks are not validated against the destination directory. A crafted tar archive served as a Kaggle resource can write files outside the intended extraction directory, allowing arbitrary file overwrite on the downloading host. The fix passes filter="data" to extractall so unsafe tar members are rejected during extraction.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and you download and extract tar-based Kaggle resources.
