At a glance
CVE-2023-40327 is a medium-severity Missing Authorization vulnerability in the Putler WordPress plugin, affecting versions <= 2.12.0. It carries a CVSS score of 5.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 2.13.0; sites on affected versions should update now. Disclosed August 2023, reported by David.
Vulnerability Overview
The Putler Connector for WooCommerce plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the putler_connector_sync_complete() function in versions up to, and including, 2.12.0. This makes it possible for unauthenticated attackers to delete the putler_connector_resync transient value.
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
Putler <= 2.12.0 carries this weakness at putler_connector_sync_complete(), 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 Putler the fix is 2.13.0: builds <= 2.12.0 are affected, anything from 2.13.0 onward is not.
Remediation
Update to version 2.13.0, 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: Putler 2.13.0 closes this, and updating the plugin is the step that ends it.
