Info Risk
📖 What Is HTTP 204?
The server successfully processed the request but is not returning any content. Commonly used for DELETE operations and form submissions that do not need a response body.
🛡️ Security Implications
Ensure DELETE endpoints returning 204 require proper authorization. A 204 on a preflight (OPTIONS) request is normal for CORS.
🔍 Common Causes
Successful DELETE, PUT, or PATCH request where no response body is needed. Also used for CORS preflight responses.
🔧 How to Fix
No fix needed. This is proper REST API behavior for operations that do not return data.
