jka Posted January 23, 2018 Share Posted January 23, 2018 A good customer called this morning and pointed an issue on the website. So, by default the store calculates Tax before checkout. This customer tried to put in a negative $$ value of the tax in the coupon code box. Say $23 in the coupon section. This brought him a discount from an existing coupon from 2 yrs back (which was still active) and gave him a big discount. The displayed coupon is a Alphanumeric coupon and not sure how entering 23 into the coupon code invoked that coupon?? How do we fix this? Not sure if just entering a random numeric number by the customer brings out previous coupons or even current ones. Thanks. Quote Link to comment Share on other sites More sharing options...
bsmither Posted January 23, 2018 Share Posted January 23, 2018 (edited) Do you know exactly what was entered? I am trying various illegal sequences of characters and not able to replicate. If you wish, send a PM with the exact code of the coupon that CubeCart eventually awarded to the order.

jka Posted January 24, 2018 Author Share Posted January 24, 2018 Hello Bsmither, I tried a few other random numbers but somehow 23 seemed invoke that coupon. We disabled that coupon for now. Not sure if there are others. Any nibbles on what you found or to fix? Quote Link to comment Share on other sites More sharing options...
bsmither Posted January 24, 2018 Share Posted January 24, 2018 Yes. I reported my findings to CubeCart. The problem is related to a few other situations. In those situations, the code has been beefed up. But the underlying problem was not attended to - maybe because it was feared that that fix would break a lot of other things. Send me a PM with the code of the coupon that came up. And you say that '23' is the trigger? I am being intentionally circumspect because I have not yet proven that this situation is benign.
