What is CVE-2026-85010?

The RestroPress plugin for WordPress is susceptible to a significant vulnerability that enables unauthenticated users to manipulate the pricing of item add-ons. Specifically, prior to version 3.4.6, the plugin fails to perform adequate validation of the item add-on price supplied by the client when items are added to or updated in the cart. This security oversight permits attackers to set an arbitrary price, potentially allowing them to complete orders for any selected total—including zero. Such flaws create serious risks for merchants who rely on this plugin, exposing them to revenue loss and fraud.

Affected Version(s)

RestroPress 0 < 3.4.6

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
