CVE-2007-4559 — TarSlip: The 15-Year Directory Traversal Educational use only. This lab intentionally exploits file system vulnerabilities inside isolated Docker containers. Do not run on any system with sensitive data or in production environments. A self-contained Docker lab that demonstrates...
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...
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...
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...

CVE-2026-62239
FlashAttention (up to 2.8.3.post1) contains a symlink attack in hopper/setup.py: download_and_copy() extracts NVIDIA toolchain archives without validating symlinks or filtering tar members. A local attacker can plant a predictable symlink in the cache to redirect extracted binaries to a chosen lo...
PYSEC-2026-2909 PraisonAI's symlink-extraction bypass of `_safe_extractall` writes outside `dest_dir`
Summary The safeextractall helper that all recipe pull, recipe publish, and recipe unpack flows route through validates each archive member's name for absolute paths, .. segments, and resolved-path escape — but does not validate member.linkname, does not reject symlink/hardlink members, and calls...

cpython: python: Extraction filter bypass for linking outside extraction directory
A flaw was found in CPython's tarfile module. This vulnerability allows bypassing of extraction filters, enabling symlink traversal outside the intended extraction directory and potential modification of file metadata via malicious tar archives using TarFile.extractall or TarFile.extract with the...
PYSEC-2026-259 Aim External Control of File Name or Path vulnerability
A vulnerability in aimhubio/aim version 3.19.3 allows an attacker to exploit the tarfile.extractall function to extract the contents of a maliciously crafted tarfile to arbitrary locations on the host server. The attacker can control repo.path and runhash to bypass directory existence checks and...
