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:
    AesCbcCryptor.prototype.decrypt = function (encryptedData) {
        var iv = this.bufferToWordArray(new Uint8ClampedArray(encryptedData.metadata));
        var data = this.bufferToWordArray(new Uint8ClampedArray(encryptedData.data));
        return AesCbcCryptor.encoder.encode(this.CryptoJS.AES.decrypt({ ciphertext: data }, this.encryptedKey, {
            iv: iv,
            mode: this.CryptoJS.mode.CBC,
        }).toString(this.CryptoJS.enc.Utf8)).buffer;
    };
