Vulnerability Overview
The WooCommerce Add to Cart Custom Redirect plugin for WordPress is vulnerable to unauthorized modification of data and loss of data due to a missing capability check on the 'wcr_dismiss_admin_notice' function in all versions up to, and including, 1.2.13. This makes it possible for authenticated attackers, with contributor access and above, to update the values of arbitrary site options to 'dismissed'.
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 interaction from a victim user. A successful exploit has high impact on integrity, availability.
CWE-862: Missing Authorization
Add to Cart Custom Redirect for WooCommerce <= 1.2.13 carries this weakness at wcr_dismiss_admin_notice, and reaching it takes an account at Contributor level or above. 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 Add to Cart Custom Redirect for WooCommerce the fix is 1.2.14: builds <= 1.2.13 are affected, anything from 1.2.14 onward is not.
Remediation
Update to version 1.2.14, 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: Add to Cart Custom Redirect for WooCommerce 1.2.14 closes this, and updating the plugin is the step that ends it.
