    Regular Expression Denial of Service (ReDoS)

    printf is a complete implementation of the printf C functions family for Node.JS, written in pure JavaScript.

    Affected versions of this package are vulnerable to Regular Expression Denial of Service (ReDoS) via the regex string /\%(?:\(([\w_.]+)\)|([1-9]\d*)\$)?([0 +\-\#]*)(\*|\d+)?(\.)?(\*|\d+)?[hlL]?([\%bscdeEfFgGioOuxX])/g in lib/printf.js. The vulnerable regular expression has cubic worst-case time complexity.

    How to fix Regular Expression Denial of Service (ReDoS)?

    Upgrade printf to version 0.6.1 or higher.
