BentoML Vulnerable to Arbitrary File Write via Symlink Path Traversal in Tar Extraction

Arbitrary File Write via Symlink Path Traversal in Tar Extraction SummaryThe safeextracttarfile function validates that each tar member's path is within the destination directory, but for symlink members it only validates the symlink's own path, not the symlink's target. An attacker can create a...

Name of the Vulnerable Software and Affected Versions FlashAttention versions prior to 2.8.3.post1 Description A symlink attack exists in the download and copy function within hopper/setup.py. The issue occurs because NVIDIA toolchain archives are extracted without validating symlinks or filterin...

Summary The safe extractall function in PraisonAI's recipe registry validates archive members against path traversal attacks but performs no checks on individual member sizes, cumulative extracted size, or member count before calling tar.extractall. An attacker can publish a malicious recipe bund...

Summary PraisonAI's recipe registry pull flow extracts attacker-controlled .praison tar archives with tar.extractall and does not validate archive member paths before extraction. A malicious publisher can upload a recipe bundle that contains ../ traversal entries and any user who later pulls that...

CVE-2026-58198

ChatterBot (Python) vulnerability CVE-2026-58198: UbuntuCorpusTrainer.extract() uses a predictable home path (~/.ubuntu_data/ubuntu_dialogs) with a check-then-create pattern, then tar.extractall(path=self.data_path). An attacker who pre-places a symlink at that path can cause archived contents to...

CVE-2026-58198 ChatterBot: Symlink-Following Arbitrary Write via UbuntuCorpusTrainer

ChatterBot is a machine learning, conversational dialog engine for creating chat bots. Prior to 1.2.14, UbuntuCorpusTrainer.extract uses a predictable home-rooted output directory /ubuntudata/ubuntudialogs with a check-then-create pattern followed by tar.extractallpath=self.datapath, allowing a...

ROS-20260709-73-0010

The vulnerability of the TarFile.ExtractToDirectory method in the .NET software platform is related to the incorrect handling of symbolic links before accessing the file. Exploiting this vulnerability could allow an attacker to gain access to and modify data...

CVE-2026-59873

node-tar is a tar archive manipulation library for Node.js. Prior to 7.5.19, node-tar does not enforce hard upper bounds on total decompressed data, entry counts, or decompression ratio in extraction and parsing paths such as src/extract.ts, allowing a small crafted gzip bomb to exhaust disk spac...

Keras Directory Traversal Vulnerability

SummaryKeras's keras.utils.getfile function is vulnerable to directory traversal attacks despite implementing filtersafepaths. The vulnerability exists because extractarchive uses Python's tarfile.extractall method without the security-critical filter="data" parameter. A PATHMAX symlink resolutio...

PYSEC-2026-1795 pip's fallback tar extraction doesn't check symbolic links point to extraction directory

When extracting a tar archive pip may not check symbolic links point into the extraction directory if the tarfile module doesn't implement PEP 706. Note that upgrading pip to a "fixed" version for this vulnerability doesn't fix all known vulnerabilities that are remediated by using a Python versi...

Kedro allows Remote Code Execution by Pulling Micro Packages

In kedro-org/kedro version 0.19.8, the pullpackage API function allows users to download and extract micro packages from the Internet. However, the function projectwheelmetadata within the code path can execute the setup.py file inside the tar file, leading to remote code execution RCE by running...

Important: python3.12

Issue Overview: The "tarfile" module would still apply normalization of AREGTYPE \x00 blocks to DIRTYPE, even while processing a multi-block member such as GNUTYPELONGNAME or GNUTYPELONGLINK. This could result in a crafted tar archive being misinterpreted by the tarfile module compared to other...

`oras-go` tar extraction: Hardlink entry with relative Linkname escapes extract dir via process CWD resolution

Root cause The tar-extraction helper ensureLinkPath at content/file/utils.go:262-275 validates that a hardlink's target resolves inside the extract base, but then returns the original unresolved target string back to the caller: go func ensureLinkPathbaseAbs, baseRel, link, target string string,...
