The decompress package for Node.js extracts archives. Prior to 10.2.1 and 11.1.3, archive extraction can create files and links outside the target directory. When extracting an archive to a directory, a crafted archive can read or write files outside that directory because hardlink and symlink entries are created without checking where targets point, path containment used a string prefix comparison, and file modes failed to remove setuid, setgid, or sticky bits. This issue is fixed in @xhmikosr/decompress versions 10.2.1 and 11.1.3.
