To fix the problem, we need to modify the regular expression to remove the ambiguity that causes exponential backtracking. Specifically, we should replace the sub-expression [a-zA-Z0-9#]+ with a more precise pattern that avoids ambiguity.
- We can replace
[a-zA-Z0-9#]+with(?:[a-zA-Z0-9]+|#+)+, which ensures that the#characters are matched in a non-ambiguous way. - This change will be made in the file
src/util/validation.json line 61.
