CWE: CWE-331 \u2014 Insufficient Entropy
The product uses an algorithm or scheme that produces insufficient entropy, leaving patterns or clusters of values that are more likely to occur than others.

Code:
    CryptorHeader.isSentinel = function (bytes) {
        if (bytes && bytes.byteLength >= 4) {
            if (bytes.toString('utf8') == CryptorHeader.SENTINEL)
                return true;
        }
    };
