To fix the problem, we need to modify the regular expression to remove the ambiguity that can lead to exponential backtracking. Specifically, we should replace the [\w]+ pattern with a more precise pattern that avoids ambiguity. One way to achieve this is to use a non-capturing group with a negated character class to ensure that each character is matched in a deterministic way.
- Replace the
[\w]+pattern with(?:[\w-]+)to ensure that the pattern matches sequences of word characters and hyphens without causing exponential backtracking. - Update the regular expression in the
pathvalidator function in thelib/envs.jsfile.
