At a glance
This record tracks a high-severity Missing Authorization vulnerability in the TK Google Fonts GDPR Compliant WordPress plugin, affecting versions <= 2.2.7. 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 2.2.8; sites on affected versions should update now. Disclosed May 2023.
Vulnerability Overview
The TK Google Fonts GDPR Compliant plugin for wordPress is vulnerable to unauthenticated plugin settings update in versions up to, and including, 2.2.7 due to missing capability checks and missing nonce checks on the `tk_google_fonts_add_font` function that can be called by unauthenticated users via the `wp_ajax_nopriv_tk_google_fonts_add_font` AJAX action.
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 TK Google Fonts GDPR Compliant <= 2.2.7 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 TK Google Fonts GDPR Compliant the fix is 2.2.8: builds <= 2.2.7 are affected, anything from 2.2.8 onward is not.
Remediation
Update to version 2.2.8, 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: TK Google Fonts GDPR Compliant 2.2.8 closes this, and updating the plugin is the step that ends it.
