At a glance
CVE-2022-3459 is a medium-severity Authorization Bypass Through User-Controlled Key vulnerability in the WooCommerce Multiple Free Gift WordPress plugin, affecting versions <= 1.2.3. It carries a CVSS score of 5.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. No fixed release has been reported yet; treat installations running this software as exposed. Disclosed September 2024, reported by Danielius Vargonas.
Vulnerability Overview
The WooCommerce Multiple Free Gift plugin for WordPress is vulnerable to gift manipulation in all versions up to, and including, 1.2.3. This is due to plugin not enforcing server-side checks on the products that can be added as a gift. This makes it possible for unauthenticated attackers to add non-gift items to their cart as a gift.
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-639: Authorization Bypass Through User-Controlled Key
Reaching this weakness in WooCommerce Multiple Free Gift <= 1.2.3 takes a caller who can reach the endpoint. Authorization bypass through a user-controlled key, often called insecure direct object reference, means the application looks up a record by an identifier from the request without checking that the caller owns it.
Changing a number in the request is enough to read or modify other users' records, which on commerce and membership sites means customer data. No fixed build of this plugin is recorded for WooCommerce Multiple Free Gift yet, so installs running <= 1.2.3 stay exposed until the vendor ships one.
Remediation
No known patch available. Please review the vulnerability's details in depth and employ mitigations based on your organization's risk tolerance. It may be best to uninstall the affected software and find a replacement.
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. No patched version is recorded yet, which is the case where a filtering layer matters most, because there is nothing to update to.
