Regular Expression Denial Of Service (ReDoS)

acorn is vulnerable to denial of service. A regex in the form of /x-\ud800/u causes the parser to enter an infinite loop as the string is not valid UTF-16 character. This results in it being sanitized before reaching the parser and when an application processes untrusted input and passes it...
