Vulnerability Overview
The Bitcoin Lightning Payment Gateway for WooCommerce (via CLINK) plugin for WordPress is vulnerable to unauthorized access due to a missing capability check on a function in versions up to, and including, 1.0.7. This makes it possible for unauthenticated attackers to perform an unauthorized action.
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
Reaching this weakness in Bitcoin Lightning Payment Gateway for WooCommerce (via CLINK) <= 1.0.7 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 Bitcoin Lightning Payment Gateway for WooCommerce (via CLINK) the fix is 1.0.8: builds <= 1.0.7 are affected, anything from 1.0.8 onward is not.
Remediation
Update to version 1.0.8, 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: Bitcoin Lightning Payment Gateway for WooCommerce (via CLINK) 1.0.8 closes this, and updating the plugin is the step that ends it.
