Attack Path

How an attacker could exploit the issue

An attacker could reach this vulnerability by uploading a malicious file through the OMGF Pro plugin. This could occur if the plugin's file upload functionality is exposed and accessible. Successful exploitation could lead to an attacker gaining significant control over the affected system.

  • No special access required.
  • Uploading a malicious file.
  • Remote code execution and data compromise.An attacker could gain access to the OMGF Pro plugin's file upload functionality through the internet. If this functionality is not properly secured, an attacker could upload a malicious file, potentially leading to remote code execution and unauthorized access to the server.
  • No special access required.
  • Uploading a malicious file.
  • Remote code execution and data compromise.

Frequently asked questions

What is OMGF Pro?

OMGF Pro is a premium plugin for WordPress used to locally host Google Fonts. By offloading these resources to a user's own server rather than fetching them from Google's servers, site administrators aim to improve website performance and enhance compliance with privacy regulations like GDPR.

What does CWE-434 mean for CVE-2026-57700?

CWE-434 refers to an 'Unrestricted Upload of File with Dangerous Type' weakness. In the context of CVE-2026-57700, this means the OMGF Pro plugin lacks sufficient validation or security checks on files being uploaded. Consequently, the system may inadvertently accept and store files that are not legitimate font files, enabling an attacker to place malicious scripts onto the server.

How does an attacker trigger this vulnerability?

An attacker triggers this flaw by interacting with the file upload functionality provided by the plugin. Because the plugin does not correctly restrict the types of files it accepts, an attacker can submit a dangerous file directly. This does not require specialized user credentials, but the vulnerability is only triggered if the upload process itself is accessible to the attacker.

Is my server at risk from this CVE?

According to Halo Surface Signal, this vulnerability is considered 'Likely' to be reachable because it resides in a WordPress plugin. Since these plugins are designed to support web-facing content, the upload interface is often exposed to the public internet. If your WordPress site uses a vulnerable version of OMGF Pro and the plugin's features are internet-accessible, your environment is potentially exposed.

What should I do if I run OMGF Pro?

Begin by verifying whether your WordPress environment uses OMGF Pro and confirming which specific version is installed. Once you have identified the presence of the plugin, determine if the relevant upload features are reachable from the network. Consult with your application owners to identify the responsible team and prepare for remediation, such as updating the plugin when a fix becomes available.
