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...

Path Traversal

Keras is vulnerable to path traversal. The vulnerability is due to the keras.utils.getfile API using Python’s tarfile.extractall without the filter="data" protection when extracting tar archives, which allows a remote attacker to craft a malicious archive with symlinks and write arbitrary files...
