CVE-2025-11087: CWE-352 Cross-Site Request Forgery (CSRF) in zozothemes Zegen Core
The Zegen Core plugin for WordPress is vulnerable to Cross-Site Request Forgery to Arbitrary File Upload in versions up to, and including, 2.0.1. This is due to missing nonce validation and missing file type validation in the '/custom-font-code/custom-fonts-uploads.php' file. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
AI Analysis
Technical Summary
CVE-2025-11087 is a CSRF vulnerability in the Zegen Core WordPress plugin (versions up to 2.0.1) caused by missing nonce validation and lack of file type validation in the '/custom-font-code/custom-fonts-uploads.php' endpoint. This flaw allows unauthenticated attackers to upload arbitrary files to the affected server by forging requests that an authenticated site administrator might unknowingly execute. Successful exploitation could lead to remote code execution on the server hosting the WordPress site.
Potential Impact
An attacker can upload arbitrary files without authentication by exploiting the CSRF vulnerability, potentially leading to remote code execution if the uploaded files are executed by the server. This compromises the confidentiality, integrity, and availability of the affected WordPress site and its hosting environment.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, administrators should avoid clicking on suspicious links and consider disabling or removing the Zegen Core plugin if possible. Monitoring for plugin updates from zozothemes is recommended to apply any forthcoming patches promptly.
