CVE-2026-7774 tarfile.data_filter path traversal bypass allows writing outside the extraction directory

tarfile.datafilter could be bypassed using crafted link entries, including symlinks with empty or directory-like names, to redirect later archive members outside the intended extraction directory. This allowed a malicious tar archive to cause tarfile.extractall to write files outside the...

Astra Linux – Vulnerability in Python 2.7, Pypy

In Lib/tarfile.py in Python 3.8.3, an attacker can create a TAR archive that causes an infinite loop when opened using tarfile.open, due to the lack of header validation in procpax...

Astra Linux – Vulnerability in python-pip

When extracting a tar archive, pip may not check symbolic links pointing into the extraction directory if the tarfile module does not implement PEP 706. Note that upgrading pip to a “fixed” version does not fix all vulnerabilities that are mitigated by using a Python version that implements PEP...

Astra Linux – Vulnerability in Python 3.11

When using TarFile.errorlevel = 0 and extracting with a filter, the documented behavior is that any filtered members would be skipped and not extracted. However, the actual behavior of TarFile.errorlevel = 0 in affected versions is that the member will still be extracted and not skipped...
