At a glance
CVE-2023-2446 is a medium-severity Exposure of Sensitive Information to an Unauthorized Actor vulnerability in the UserPro - Community and User Profile WordPress Plugin WordPress plugin, affecting versions <= 5.1.1. It carries a CVSS score of 6.5 (reachable over the network; low attack complexity; high confidentiality impact). 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 sensitive information disclosure via the 'userpro' shortcode in versions up to, and including 5.1.1. 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.
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
UserPro - Community and User Profile WordPress Plugin <= 5.1.1 carries this weakness at userpro, and reaching it 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 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?
The fix is the thing that ends this: UserPro - Community and User Profile WordPress Plugin 5.1.2 closes this, and updating the plugin is the step that ends it.
