CVE-2025-11171
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 Chartify – WordPress Chart Plugin for WordPress is vulnerable to Missing Authentication for Critical Function in all versions up to, and including, 3.5.9. This is due to the plugin registering an unauthenticated AJAX action that dispatches to admin-class methods based on a request parameter, without any nonce or capability checks. This makes it possible for unauthenticated attackers to execute administrative functions via the wp-admin/admin-ajax.php endpoint granted they can identify callable method names.
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 · high confidenceThe Chartify WordPress plugin registers an unauthenticated AJAX action at wp-admin/admin-ajax.php that dispatches to admin-class methods based on a request parameter. No nonce verification or capability checks are performed, allowing unauthenticated attackers to invoke administrative functions by knowing callable method names.

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.
-
Locate Chartify plugin filesCheck for the Chartify plugin directory in your WordPress installation at wp-content/plugins/chartify/ or search for chartify.phpAffected if Plugin files are present in the WordPress plugins directory
-
Identify installed versionOpen wp-content/plugins/chartify/chartify.php and locate the 'Version' header comment in the plugin file headerAffected if Version number is found and is lower than 3.6.0 (e.g., 3.5.0, 3.4.0, etc.)
-
Verify plugin is activeIn WordPress admin, go to Plugins > Installed Plugins and confirm Chartify is activated, or query the wp_options table for option_name = 'active_plugins'Affected if Plugin is currently activated on the site
-
Confirm admin-ajax endpoint exposureTest if the Chartify AJAX action is reachable by sending a request to wp-admin/admin-ajax.php with action=chartify_[method_name] (where method name would need to be determined from plugin code)Affected if Requests to admin-ajax.php with Chartify actions complete without requiring authentication
If Chartify plugin is installed, activated, and version is below 3.6.0, the site is vulnerable to unauthenticated privilege escalation via the AJAX endpoint.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpdate to version 3.6.0 or later which should include authentication and capability checks. If no update is available, disable the plugin or restrict admin-ajax.php access at the server level as a temporary workaround.
