A flaw was found in the JSZip package. Affected versions of JSZip could allow a remote attacker to traverse directories on the system caused by the failure to sanitize filenames when files are loaded with `loadAsync`, which makes the library vulnerable to a Zip Slip attack. By extracting files from a specially crafted archive, an attacker could gain access to parts of the file system outside of the target folder, overwrite the executable files, and execute arbitrary commands on the system.
