BIT-LIBPYTHON-2025-4517 Arbitrary writes via tarfile realpath overflow

Allows arbitrary filesystem writes outside the extraction directory during extraction with filter="data". You are affected by this vulnerability if using the tarfile module to extract untrusted tar archives using TarFile.extractall or TarFile.extract using the filter= parameter with a value of...

cpython: Tarfile extracts filtered members when errorlevel=0

A flaw was found in CPython's tarfile module. This vulnerability allows unauthorized file extraction via crafted tar archives when TarFile.errorlevel=0, bypassing expected filtering mechanisms...

cpython: python: Bypassing extraction filter to create symlinks to arbitrary targets outside extraction directory

A flaw was found in the Python tarfile module. This vulnerability allows attackers to bypass extraction filters, enabling symlink targets to escape the destination directory and allowing unauthorized modification of file metadata via the use of TarFile.extract or TarFile.extractall with the filte...
