At a glance
CVE-2023-5134 is a medium-severity Exposure of Sensitive Information to an Unauthorized Actor vulnerability in the Easy Registration Forms WordPress plugin, affecting versions <= 2.1.1. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Subscriber level or above. No fixed release has been reported yet; treat installations running this software as exposed. Disclosed September 2023, reported by István Márton.
Vulnerability Overview
The Easy Registration Forms for WordPress is vulnerable to Information Disclosure via the 'erforms_user_meta' shortcode in versions up to, and including, 2.1.1 due to insufficient controls on the information retrievable via the shortcode. This makes it possible for authenticated attackers, with subscriber-level capabilities or above, to retrieve arbitrary sensitive user meta.
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.
CWE-200: Exposure of Sensitive Information to an Unauthorized Actor
Easy Registration Forms <= 2.1.1 carries this weakness at erforms_user_meta, and reaching it takes an account at Subscriber level or above. 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. No fixed build of this plugin is recorded for Easy Registration Forms yet, so installs running <= 2.1.1 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.
