CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Reaching this weakness in Advanced Order Export For WooCommerce <= 3.1.7 takes a caller who can reach the endpoint. Cross-site scripting happens when input from a request is written into a page without being escaped for the context it lands in, so the browser parses attacker-supplied text as markup or script.

For Advanced Order Export For WooCommerce the fix is 3.1.8: builds <= 3.1.7 are affected, anything from 3.1.8 onward is not.
