Deferred Deferred - Pending Action
Cross-Site Request Forgery in Auto Making JSON-LD WordPress Plugin

Publication date: 2026-05-27

Last updated on: 2026-05-27

Assigner: Wordfence

Description
The auto making JSON-LD plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 4.5.3. This is due to missing or incorrect nonce validation on the amJL_certification function. This makes it possible for unauthenticated attackers to update the plugin's license key option, and subsequently trigger license validation and pro feature installation on the victim site without the administrator's consent via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. Successful exploitation can trigger downstream calls to amJL_is_license_valid() and amJL_download_and_install_pro_features(), meaning the impact extends beyond a simple settings change to unauthorized installation of plugin components.

Mitigation Strategies

The vulnerability exists in all versions up to and including 4.5.3 of the auto making JSON-LD plugin for WordPress due to missing or incorrect nonce validation. Immediate mitigation steps include updating the plugin to a version later than 4.5.3 where this issue is fixed.

Additionally, administrators should avoid clicking on suspicious links that could trigger forged requests and consider disabling or removing the vulnerable plugin until an update is applied.

Executive Summary

The auto making JSON-LD plugin for WordPress has a Cross-Site Request Forgery (CSRF) vulnerability in all versions up to and including 4.5.3. This vulnerability exists because the plugin's amJL_certification function lacks proper nonce validation. As a result, an attacker can trick a site administrator into performing an action, such as clicking a malicious link, which allows the attacker to update the plugin's license key option without authorization.

Exploitation of this vulnerability can lead to unauthorized triggering of license validation and installation of pro features on the victim's site, extending the impact beyond just changing settings to installing plugin components without consent.

Impact Analysis

This vulnerability can allow an unauthenticated attacker to update the license key option of the plugin on your WordPress site without your consent.

As a consequence, the attacker can trigger license validation and install pro features of the plugin without authorization, potentially altering your site’s functionality or introducing unwanted components.
