The quantifier '[0-9.:]+' can exchange characters with '[0-9-+:]+'. Using any string accepted by /[\d:]+/i, this can be exploited to cause at least polynomial backtracking. This might cause exponential backtracking

The quantifier '[0-9.:]+' can exchange characters ([\d:]) with '[0-9-+:]+'. This makes the capturing group misleading, because the quantifier will capture fewer characters than its pattern suggests

The quantifier '[0-9]{1,2}' can exchange characters (\d) with '[0-9]{1,2}'. This makes the capturing group misleading, because the quantifier will capture fewer characters than its pattern suggests

The quantifier '[0-9]{1,2}' can exchange characters (\d) with '[0-9]{1,4}'. This makes the capturing group misleading, because the quantifier will capture fewer characters than its pattern suggests

The quantifier '[0-9]{1,2}' can exchange characters (\d) with '[0-9]{1,4}'. This makes the capturing group misleading, because the quantifier will capture fewer characters than its pattern suggests
