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:
function __processMessage(modules, message) {
    if (!modules.cryptoModule)
        return message;
    try {
        var decryptedData = modules.cryptoModule.decrypt(message);
        var decryptedPayload = decryptedData instanceof ArrayBuffer ? JSON.parse(new TextDecoder().decode(decryptedData)) : decryptedData;
        return decryptedPayload;
    }
    catch (e) {
        if (console && console.log)
            console.log('decryption error', e.message);
        return message;
    }
}
