Overview

Unsafe CORS configuration may lead to the data being compromised.

CORS (Cross Origin Resource Policy) is a mechanism defined in the HTML5 standard that enables JavaScript-code to work with data from another domain. CORS parameters must be defined in the HTTP header Access-Control-Allow-Origin.

CORS parameter defined not precisely enough may lead to the application data being compromised.
