NVD Description

Note: Versions mentioned in the description apply only to the upstream label-studio package and not the label-studio package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

jaraco.context, an open-source software package that provides some useful decorators and context managers, has a Zip Slip path traversal vulnerability in the jaraco.context.tarball() function starting in version 5.2.0 and prior to version 6.1.0. The vulnerability may allow attackers to extract files outside the intended extraction directory when malicious tar archives are processed. The strip_first_component filter splits the path on the first / and extracts the second component, while allowing ../ sequences. Paths like dummy_dir/../../etc/passwd become ../../etc/passwd. Note that this suffers from a nested tarball attack as well with multi-level tar files such as dummy_dir/inner.tar.gz, where the inner.tar.gz includes a traversal dummy_dir/../../config/.env that also gets translated to ../../config/.env. Version 6.1.0 contains a patch for the issue.
