node-fetch Inefficient Regular Expression Complexity

node-fetch is a light-weight module that brings window.fetch to node.js.

Affected versions of this package are vulnerable to Regular Expression Denial of Service (ReDoS) in the isOriginPotentiallyTrustworthy() function in referrer.js, when processing a URL string with alternating letters and periods, such as 'http://' + 'a.a.'.repeat(i) + 'a'.
