CVE-2026-59974

Stanza is a Stanford NLP Python library. Prior to 1.14.0 , the function stanza.resources.common.unzip in stanza/resources/common.py passes downloaded model and resource archives to zipfile.ZipFile.extractall without validating member paths. The vulnerable extraction path is reachable through stan...

Astra Linux – Vulnerability in Python 3.11

It allows the extraction filter to be ignored, enabling symlink targets to point outside the destination directory, and modifying some file metadata. This vulnerability affects users who use the TarFile module to extract untrusted tar archives using TarFile.extractall or TarFile.extract, with the...

python: cpython: CPython: tarfile extraction filter bypass allows escaping the destination directory

A flaw was found in the tarfile.extractall function within Python. A remote attacker could exploit this vulnerability by providing a specially crafted archive. This archive could bypass security filters by using a hardlink that references a symlink, allowing the symlink to be recreated outside th...

BIT-PYTHON-2026-11940 tarfile extraction filter bypass allows escaping the destination directory

tarfile.extractall with the 'data' or 'tar' filter could be bypassed by a crafted archive where a hardlink references a symlink stored at a deeper name than the hardlink itself. The extraction fallback validated the symlink at it's archived location but recreated it at the hardlink's shallower...
