QID 980693

QID 980693: Nodejs (npm) Security Update for node-krb5 (GHSA-4v9q-hm2p-68c4)

Affected versions of `node-krb5` do not validate the KDC prior to authenticating, which might allow an attacker with network access and enough time to spoof the KDC and impersonate a valid user without knowing their credentials.

## Recommendation

It appears that this will remain unfixed indefinitely, as the Github issue for this vulnerability has been open since 2015, with no work on it since then.

At this time, the best available mitigation is to use an alternative module that is actively maintained and provides similar functionality. There are [multiple modules fitting this criteria available on npm.](https://www.npmjs.com/search?q=kerberos).

Successful exploitation of this vulnerability may affect the confidentiality, integrity, and availability of the targeted user.

CVSS V3 rated as Medium - 4.2 severity.
