At a glance
CVE-2023-6007 is a high-severity Missing Authorization vulnerability in the UserPro - Community and User Profile WordPress Plugin WordPress plugin, affecting versions <= 5.1.1. It carries a CVSS score of 7.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 5.1.2; sites on affected versions should update now. Disclosed November 2023, reported by István Márton.
Vulnerability Overview
The UserPro plugin for WordPress is vulnerable to unauthorized access of data, modification of data, loss of data due to a missing capability check on multiple functions in all versions up to, and including, 5.1.1. This makes it possible for unauthenticated attackers to add, modify, or delete user meta and plugin options.
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 UserPro - Community and User Profile WordPress Plugin <= 5.1.1 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 UserPro - Community and User Profile WordPress Plugin the fix is 5.1.2: builds <= 5.1.1 are affected, anything from 5.1.2 onward is not.
Remediation
Update to version 5.1.2, 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: UserPro - Community and User Profile WordPress Plugin 5.1.2 closes this, and updating the plugin is the step that ends it.
