CWE-20: Improper Input Validation

Reaching this weakness in Bonus for Woo <= 7.6.6 takes a caller who can reach the endpoint. Improper input validation means the application accepts input without confirming it has the form, type or range the code downstream assumes.

The concrete impact depends on where the unvalidated value lands, which is why records in this class range from cosmetic bugs to full compromise. For Bonus for Woo the fix is 7.6.7: builds <= 7.6.6 are affected, anything from 7.6.7 onward is not.
