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:
    CryptoModule.prototype.encrypt = function (data) {
        var encrypted = this.defaultCryptor.encrypt(data);
        if (!encrypted.metadata)
            return encrypted.data;
        var headerData = this.getHeaderData(encrypted);
        return this.concatArrayBuffer(headerData, encrypted.data);
    };
