Overview

An untrusted regular expression is any regexp containing patterns sourced from user input.

Ruby’s built-in regular expression library allows patterns which complete in exponential time, permitting denial-of-service attacks.

Not all regular expression features are available in untrusted regexes, and there is a strict limit on total execution time. See the RE2 documentation at github.com/google/re2/wiki/Syntax for more details.

This class doesn’t change any instance variables, which allows it to be frozen and setup in constants.

This class only provides support replacing matched token with a block (like ‘gsub`).
