  "description": "Composer is a dependency Manager for the PHP language. Prior to 2.2.29 and 2.10.2, a Composer package bin entry containing .. path segments can resolve outside the package install directory and cause Composer\u0027s binary installation flow to chmod an existing host file to a world-readable and world-executable mode during composer install, update, or require.
