JSON hijacking definition
Real-life JSON hijacking examples
One notable example of JSON hijacking involved social networking sites that exposed user profile data through JSONP endpoints without proper security measures. Attackers exploited this vulnerability to harvest users’ personal information and perform targeted phishing attacks.
JSON hijacking prevention
- Avoid exposing sensitive information in JSON responses, or use additional authentication and encryption mechanisms to protect the data.
- Implement proper input validation and output encoding to prevent injection attacks.
- Enforce strict content security policies to restrict the execution of external scripts.
- Implement strong session management and use anti-CSRF (Cross-Site Request Forgery) techniques to prevent unauthorized requests.
- Regularly update web application frameworks and libraries to incorporate the latest security patches and best practices.
