What is JSON injection? ›
JSON injection is a vulnerability that lets a malicious hacker inject malicious data into JSON streams or use malicious JSON streams to modify application behavior.
How to reduce JSON response? ›Compressing with gzip
As text data, JSON data compresses nicely. That's why gzip is our first option to reduce the JSON data size. Moreover, it can be automatically applied in HTTP, the common protocol for sending and receiving JSON.
To prevent server-side JSON injections, sanitize all data before serializing it to JSON. For example, if you use Java, a good option to sanitize JSON data is to use the OWASP JSON Sanitizer. The best method to prevent client-side JSON injections is never to use the eval function to evaluate JSON data.
Which solutions are useful to process JSON data securely? ›What are the most important API security best practices for JSON web services?
- Use HTTPS and SSL/TLS.
- Validate input and output.
- Implement authentication and authorization.
- Apply rate limiting and throttling.
- Use logging and monitoring.
- Update and test regularly.
- Here's what else to consider.

JavaScript Object Notation (JSON) is a standard text-based format for representing structured data based on JavaScript object syntax. It is commonly used for transmitting data in web applications (e.g., sending some data from the server to the client, so it can be displayed on a web page, or vice versa).
What are the security risks of JSON? ›Cyber vulnerabilities often stem from how JSON data is handled and parsed. For instance, without proper validation, JSON data can be manipulated to conduct injection attacks. According to OWASP, Injection flaws, such as SQL, NoSQL, Command, and Object Injection, still remain one of the most critical web security risks.
How do you handle JSON response error? ›The following configuration options are available in the JSON Error Contents section: Show detailed explanation of error: Select this option to return a detailed explanation of the JSON error in the error message. This makes it possible to suppress the reason for the exception in a tightly locked down system.
How to optimize a JSON? ›By Minimizing JSON Size
- remove unnecessary spaces and line breaks.
- Use shorter key names when you can.
- For the transmission, employ compression algorithms such as Brotli or Gzip.

Limitations of JSON format
- No error handling - JSON has no error handling mechanism for JSON calls. ...
- No comments - These two words are enough to make the developer's life difficult.
- Security - JSON can be dangerous if used with untrusted browsers or services.
JSON hijacking allows an attacker to send a GET request via a malicious web site or similar attack vector and utilize a user's stored credentials to retrieve sensitive or protected data to which that user has access.
How to fix JSON errors? ›
To fix a JSON parse error in Python, you should convert the objects to have a JSON-like structure, enclose keys with double quotes, replace Python constants with their JSON equivalents, strip trailing commas and comments, and concatenate strings.
Is JSON hijacking still an issue? ›Note: Older Browsers were more vulnerable to JSON Hijacking. As of now, this vulnerability has been fixed in modern Browsers.
How to protect JSON data? ›To encrypt JSON data, employ encryption methods like symmetric (e.g., AES, DES), utilizing a shared key for both encryption and decryption. Asymmetric encryption (e.g., RSA, ECC) uses a public-private key pair.
What is the best database to store JSON? ›The best database for JSON
The syntax is simple and readable for anyone. A JSON database like MongoDB stores the data in a JSON-like format (binary JSON), which is the binary encoded version of JSON, and is optimized for performance and space. This makes the MongoDB database the best natural fit for storing JSON data.
The most basic way to persist a JSON object in a relational database is to convert the object into a String before persisting it. Then, we convert it back into an object when we retrieve it from the database.
What is JSON and what does it do? ›JSON stands for JavaScript Object Notation. JSON is a lightweight format for storing and transporting data. JSON is often used when data is sent from a server to a web page. JSON is "self-describing" and easy to understand.
What does JSON sanitizer do? ›The Open Web Application Security Project (OWASP) JavaScript Object Notation (JSON) Sanitizer software converts JSON-like content into genuine JSON content. The product can also provide some reviewing of code before embedding the JSON code into Hypertext Markup Language (HTML) or Extensible Markup Language (XML) code.
