CVE-2025-6553
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 · uneditedThe Ovatheme Events Manager plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the process_checkout() function in all versions up to, and including, 1.8.5. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible.

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 checksWork through these to decide whether this CVE applies to you.
-
Confirm plugin installationIn WordPress admin, go to Plugins > Installed Plugins and look for 'Ovatheme Events Manager' or check the plugin directory /wp-content/plugins/ for a folder containing 'ova' or 'events-manager' in the nameAffected if The plugin is present on the WordPress site
-
Identify installed versionIn WordPress admin, click on the plugin to view details and read the version number, or check the main plugin PHP file for a 'Version:' comment headerAffected if The version is unknown or falls within any unpatched range compared to the fixed version
-
Check if checkout feature is accessibleExamine the plugin files for the process_checkout() function and determine if the checkout functionality is publicly accessible (look for hooks like add_action('init', 'process_checkout') without authentication checks)Affected if The process_checkout function exists and can be triggered without authentication
-
Review uploaded files directoryCheck /wp-content/uploads/ and any events-manager specific upload folders for unexpected file types (PHP, .exe, .phtml, .php5, .php7, .htaccess) especially in directories created after the vulnerability disclosure dateAffected if Suspicious executable files are found in upload directories that were not intentionally uploaded by administrators
-
Check server access logsReview web server access logs (Apache/Nginx) for POST requests to checkout-related endpoints containing file upload patterns, looking for requests with unusual file extensions from unknown IP addressesAffected if Multiple POST requests with file uploads are seen from external IPs to checkout endpoints, especially with PHP or other executable extensions
If the Ovatheme Events Manager plugin is installed and the process_checkout function is exposed without authentication, the site is likely affected by this arbitrary file upload vulnerability.
