Description Pedro Sampaio 2018-02-16 15:56:37 EST 
A flaw was discovered in is-myjson-valid before 1.4.1 and 2.17.2. Affected versions of this package are vulnerable to Regular Expression Denial of Service (ReDoS) attacks. It used a regular expression (/^\S+@\S+$/) in order to validate emails. This can cause an impact of about 10 seconds matching time for data 90K characters long.
