At a glance
CVE-2023-0814 is a medium-severity Exposure of Sensitive Information to an Unauthorized Actor vulnerability in the User Profile Builder WordPress plugin, affecting versions <= 3.9.0. It carries a CVSS score of 6.5 (reachable over the network; low attack complexity; high confidentiality impact). The issue is fixed in version 3.9.1; sites on affected versions should update now. Disclosed February 2023, reported by István Márton.
Vulnerability Overview
The Profile Builder – User Profile & User Registration Forms plugin for WordPress is vulnerable to sensitive information disclosure via the [user_meta] shortcode in versions up to, and including 3.9.0. This is due to insufficient restriction on sensitive user meta values that can be called via that shortcode. This makes it possible for authenticated attackers, with subscriber-level permissions, and above to retrieve sensitive user meta that can be used to gain access to a high privileged user account. This does require the Usermeta shortcode be enabled to be exploited.
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 confidentiality.
CWE-200: Exposure of Sensitive Information to an Unauthorized Actor
Reaching this weakness in User Profile Builder <= 3.9.0 takes a caller who can reach the endpoint. Sensitive information exposure means data the application intended to keep internal is returned to a caller who should not be able to see it.
The disclosed data — credentials, tokens, customer records or internal paths — is usually worth more as material for a follow-up attack than as an end in itself. For User Profile Builder the fix is 3.9.1: builds <= 3.9.0 are affected, anything from 3.9.1 onward is not.
Remediation
Update to version 3.9.1, or a newer patched version
How does WordSec protect against this?
The fix is the thing that ends this: User Profile Builder 3.9.1 closes this, and updating the plugin is the step that ends it.
