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:
  handleResponse: async ({ PubNubFile, config, cryptography, cryptoModule }, res, params) => {
    let { body } = res.response;
    if (PubNubFile.supportsEncryptFile && (params.cipherKey || cryptoModule)) {
      body =
        params.cipherKey == null
          ? (await cryptoModule.decryptFile(PubNubFile.create({ data: body, name: params.name }), PubNubFile)).data
          : await cryptography.decrypt(params.cipherKey ?? config.cipherKey, body);
    }

    return PubNubFile.create({
      data: body,
      name: res.response.name ?? params.name,
      mimeType: res.response.type,
    });
  },
