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...

CVE-2026-62239 FlashAttention Symlink Attack via tarfile.extractall in hopper/setup.py

FlashAttention through 2.8.3.post1, fixed in commit 0816ef1, contains a symlink attack vulnerability in the downloadandcopy function within hopper/setup.py that extracts NVIDIA toolchain archives without validating symlinks or filtering tar members. A local attacker can pre-plant a symlink in the...

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...

PraisonAI's symlink-extraction bypass of `_safe_extractall` writes outside `dest_dir`

SummaryThe 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...
