Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Unrestricted Upload of File with Dangerous Type vulnerability in Daan.Dev OMGF Pro allows Using Malicious Files. This issue affects OMGF Pro: from n/a through 5.2.6.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

The OMGF Pro plugin contains an unrestricted file upload vulnerability (CWE-434) allowing attackers to upload malicious files (e.g., PHP shells) directly to the server. With a CVSS 10 rating, this typically enables remote code execution by accessing the uploaded malicious file via web request.

MitigationImmediate mitigation requires disabling the file upload functionality or the entire plugin until a patched version is available. Organizations should deploy WAF rules to block executable file uploads and implement strict allowlist-based file type validation on the server side.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Verify OMGF Pro plugin installation and version
    In WordPress admin, go to Plugins > Installed Plugins and locate 'OMGF Pro' or 'OMGF Pro | Manage, Host Google Fonts Locally'. Note the version number displayed. Alternatively, check the plugin header in /wp-content/plugins/omgf-pro/omgf-pro.php for the 'Version' comment.
    Affected if The plugin is installed and the version is within the affected range (compare to official CVE advisory once published)
  2. Inspect plugin upload directories for suspicious files
    Check the OMGF Pro upload directory (typically /wp-content/uploads/omgf/) and any cached font directories for unexpected file types. Look for files with .php, .phtml, .exe, or other executable extensions that were not intentionally uploaded by an administrator.
    Affected if Unexpected PHP files or other executable scripts are found in the plugin's upload directories
  3. Review web server access logs for upload endpoint requests
    Examine web server logs (Apache access.log, Nginx access.log) for POST requests to the OMGF Pro file upload handler. Look for requests to paths like /wp-json/omgf/v1/upload or similar endpoints that accept file uploads.
    Affected if POST requests to upload endpoints exist from unauthorized or unexpected IP addresses, or with unusual file types
  4. Check file upload permissions and settings
    In WordPress admin, navigate to OMGF Pro settings and review any file upload-related options. Check if the plugin's upload functionality is enabled and accessible to non-administrator users.
    Affected if File upload functionality is enabled and accessible to users with low privilege levels (subscriber, contributor)

A user is affected if OMGF Pro plugin is installed with file upload functionality enabled and the installed version falls within the vulnerable version range, or if suspicious executable files are found in plugin-managed directories.

Mitigation

Immediate mitigation requires disabling the file upload functionality or the entire plugin until a patched version is available. Organizations should deploy WAF rules to block executable file uploads and implement strict allowlist-based file type validation on the server side.
