CVE-2025-7841 in Certificate & Badge Maker Plugin
Summary
by MITRE • 08/23/2025
The Sertifier Certificate & Badge Maker for WordPress – Tutor LMS plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.19. This is due to missing or incorrect nonce validation on the 'sertifier_settings' page. This makes it possible for unauthenticated attackers to update the plugin's api key via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

The vulnerability identified as CVE-2025-7841 affects the Sertifier Certificate & Badge Maker plugin for WordPress, which is integrated with the Tutor LMS learning management system. This plugin facilitates the creation of certificates and badges for educational content within the WordPress ecosystem. The vulnerability exists in all versions up to and including 1.19, representing a critical security weakness that could compromise the integrity of educational platforms relying on this functionality.
The technical flaw stems from the absence of proper nonce validation on the 'sertifier_settings' page within the plugin's administrative interface. Nonce values serve as cryptographic tokens that verify the authenticity of requests and prevent unauthorized modifications to system configurations. In this case, the plugin fails to implement proper validation mechanisms, allowing attackers to forge requests that modify critical settings without proper authentication. This represents a direct violation of the principle of least privilege and proper access control enforcement.
The operational impact of this Cross-Site Request Forgery vulnerability extends beyond simple configuration changes. An unauthenticated attacker who successfully tricks a site administrator into clicking a malicious link could gain unauthorized access to modify the plugin's API key, potentially compromising the entire certificate generation system. This could lead to unauthorized certificate issuance, data manipulation, or even complete system compromise if the API key provides access to external services or databases. The vulnerability particularly affects educational institutions and training organizations that rely on automated certificate generation, as it undermines the trustworthiness of their digital credentials.
This vulnerability maps directly to CWE-352, which specifically addresses Cross-Site Request Forgery weaknesses in web applications. The flaw also aligns with ATT&CK technique T1566, which covers social engineering tactics including the manipulation of web browsers to execute unauthorized commands. The absence of proper nonce validation creates a vector for attackers to perform privilege escalation attacks and potentially establish persistent access to the WordPress administration interface. Organizations should immediately update to the latest plugin version, implement additional security measures such as role-based access controls, and consider network segmentation to limit the potential impact of such vulnerabilities. Regular security audits and penetration testing should be conducted to identify similar weaknesses in other plugins and themes within the WordPress ecosystem.
