Vulnerability Details

acorn is vulnerable to REGEX DoS. A regex of the form /[x-\ud800]/u causes the parser to enter an infinite loop. attackers may leverage the vulnerability leading to a Denial of Service since the string is not valid UTF16 and it results in it being sanitized before reaching the parser.
