CVE-2024-0617 is a medium-severity Missing Authorization vulnerability in the Simple Discount Rules for Woocommerce WordPress plugin, affecting versions <= 4.12.

Vulnerability Overview
The Category Discount Woocommerce plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the wpcd_save_discount() function in all versions up to, and including, 4.12. This makes it possible for unauthenticated attackers to modify product category discounts that could lead to loss of revenue.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site, and no interaction from a victim user.
CWE-862: Missing Authorization
Simple Discount Rules for Woocommerce <= 4.12 carries this weakness at wpcd_save_discount(), and reaching it takes a caller who can reach the endpoint. A missing authorization check means a function is reachable by anyone who can reach the endpoint, because the code never asks whether the caller is allowed to perform the action.
Any user who can reach the endpoint gets to run an action reserved for higher-privileged roles, from reading protected data to changing settings or content. For Simple Discount Rules for Woocommerce the fix is 4.13: builds <= 4.12 are affected, anything from 4.13 onward is not.
Remediation
Update to version 4.13, or a newer patched version
How does WordSec protect against this?
Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: Simple Discount Rules for Woocommerce 4.13 closes this, and updating the plugin is the step that ends it.
