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 {
    const decryptedData = modules.cryptoModule.decrypt(message);
    const 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;
  }
}
