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...

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...

python: cpython: Arbitrary writes via tarfile realpath overflow

A flaw was found in the CPython tarfile module. This vulnerability allows arbitrary filesystem writes outside the extraction directory via extracting untrusted tar archives using the TarFile.extractall or TarFile.extract methods with the extraction filter parameter set to "data" or "tar"...

Path traversal, lead to remote code execution

Description clearml's safeextract is actually ​​NOT secure​​. It fails to properly handle symbolic links and hard links. When these links point to files ​​outside the TAR archive​​, it can lead to ​​arbitrary file writes​​, potentially resulting in ​​remote code execution​​. Due to a change in th...

Path traversal, lead to remote code execution

Description In zenml's PathMaterializer class, the load function uses ispathwithindirectory to validate files during data.tar.gz extraction. While this prevents path traversal vulnerabilities, it fails to effectively detect symbolic and hard links. with tarfile.openarchivepathlocal, "r:gz" as tar...

Security issues fixed: CVE-2025-4517: arbitrary filesystem writes outside the extraction directory during extraction with filter="data" bsc1244032 CVE-2025-4516: use-after-free in the unicode-escape decoder when using...

Towards Provable (In)Secure Model Weight Release Schemes

Recent secure weight release schemes claim to enable open-source model distribution while protecting model ownership and preventing misuse. However, these approaches lack rigorous security foundations and provide only informal security guarantees. Inspired by established works in cryptography, we...

FORGE: an LLM-Driven Framework for Large-Scale Smart Contract Vulnerability Dataset Construction

High-quality smart contract vulnerability datasets are critical for evaluating security tools and advancing smart contract security research. Two major limitations of current manual dataset construction are 1 labor-intensive and error-prone annotation processes limiting the scale, quality, and...
