> DESCRIPTION

extract-zip through 2.0.1 containment-checks only the parent directory of each archive entry and never the entry's own final path component, so an archive containing two entries with identical names - a symlink whose target is outside the destination, followed by a regular file - writes through the planted symlink and yields an arbitrary file write outside the destination directory.

CWE-22 CWE-59

> CWE DETAILED DESCRIPTIONS

CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') - The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. | CWE-59: Improper Link Resolution Before File Access ('Link Following') - The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.
