Inefficient Regular Expression Complexity in node-fetch/node-fetch

Collected exploitation and prediction evidence

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

[node-fetch](https://www.npmjs.com/package/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'`.
