At a glance

CVE-2024-12542 is a high-severity Missing Authorization vulnerability in the linkID WordPress plugin, affecting versions <= 0.1.2. It carries a CVSS score of 8.6 (reachable over the network; low attack complexity; high confidentiality impact). Exploitation requires no authentication. No fixed release has been reported yet; treat installations running this software as exposed. Disclosed January 2025, reported by Francesco Carlucci.

Vulnerability Overview

The linkID plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check when including the 'phpinfo' function in all versions up to, and including, 0.1.2. This makes it possible for unauthenticated attackers to read configuration settings and predefined variables on the site's server. The plugin does not need to be activated for the vulnerability 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 privileges on the target site, and no interaction from a victim user. A successful exploit has high impact on confidentiality.

CWE-862: Missing Authorization

linkID <= 0.1.2 carries this weakness at phpinfo, and reaching it takes no account at all. 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. No fixed build of this plugin is recorded for linkID yet, so installs running <= 0.1.2 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.

How does WordSec protect against this?

This one needs no account at all, which puts it outside what login hardening can reach; WordSec's login security narrows the account-level paths around it, and the firewall is what inspects the request itself. No patched version is recorded yet, which is the case where a filtering layer matters most, because there is nothing to update to.
