GHSA-g3qw-9pgp-xpj4 Out-of-bounds Read in njwt

• npm njwt: < 1.0.0 → fixed in 1.0.0

Versions of `njwt` prior to 1.0.0 are vulnerable to out-of-bounds reads when a number is passed into the `base64urlEncode` function. On Node.js 6.x or lower this can expose sensitive information and on any other version of Node.js this creates a Denial of Service vulnerability. Recommendation Upgrade to version 1.0.0.
