This PR adds a new eslint rule that flags the usage of
new RegExp()
constructor calls. The purpose of this rule is to make us aware of the potential danger of creating a regular expression from (end) user input. This has led to security incidents in the past.To be clear, it is perfectly okay to ignore this rule in cases where we're sure that there's no danger or where input is already escaped.
We have other rules (+CodeQL) in place to avoid RegExp usage with static expressions but these didn't cover regular expressions where the expression itself or the flags were constructed from variables.
