The package printf before 0.6.1 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.
Weakness
The product uses a regular expression with a worst-case computational complexity that is inefficient and possibly exponential.
