HDWebmobile Order Bump
A one-click discounted add-on offer at checkout — the price charged is always the admin’s own configured price, never accepted from the request.
Overview
HDWebmobile Order Bump shows one extra product at a discount on the cart page. A shopper clicks a single link to add it — no form, no quantity field, nothing to submit — and the discounted price is computed by the server at that moment from the product’s own regular price and your configured discount percentage.
Several competing “order bump” and “one-click upsell” plugins have computed the bumped item’s discounted price on the checkout page and then read that price back from a hidden form field when the order was placed (CWE-20, Improper Input Validation). A shopper who edited that field, or simply replayed the request with a different value, could add the bump item at almost any price of their choosing. This plugin has no such field to tamper with in the first place: adding the offer is a plain link, not a form — there is nothing to submit a price through. The discounted price is computed by one method, get_discounted_price(), which takes no arguments at all. It always derives the price fresh from the product’s own current regular price and the store’s saved discount percentage. That same method is called again every time cart totals are calculated, so the price is never “locked in” from whenever the item was added — and if the store owner later points the offer at a different product, a leftover item from the old offer reverts to its own real price rather than keeping a stale discount.
