CVE-2025-14437
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 Hummingbird Performance plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 3.18.0 via the 'request' function. This makes it possible for unauthenticated attackers to extract sensitive data including Cloudflare API credentials.
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 Hummingbird Performance WordPress plugin has a sensitive information exposure vulnerability in its 'request' function affecting all versions up to 3.18.0. This flaw allows unauthenticated attackers to make requests that expose sensitive data, specifically including Cloudflare API credentials stored by the plugin.

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 Hummingbird Performance plugin is installedCheck the WordPress plugins directory at wp-content/plugins/hummingbird-performance/ or view the installed plugins in the WordPress admin dashboardAffected if The plugin directory or admin listing shows Hummingbird Performance as an active or installed plugin
-
Identify the installed plugin versionOpen the main plugin file (typically hummingbird-performance.php) or the readme.txt file in the plugin directory and locate the version header commentAffected if The version number found is 3.18.0 or any earlier version (e.g., 3.17.0, 3.16.0, etc.)
-
Verify if Cloudflare API credentials are storedCheck the WordPress database wp_options table for option names containing 'cloudflare' or 'api_key', or inspect the plugin settings via WP-Admin under Hummingbird Performance > CloudflareAffected if Cloudflare API credentials, API keys, or tokens are configured and saved in the plugin settings or database
-
Test for the vulnerable request endpointSend a crafted HTTP request to the plugin's AJAX endpoint or REST API route that corresponds to the 'request' function (commonly /wp-admin/admin-ajax.php?action=hummingbird_request or similar), without authenticationAffected if The endpoint responds with sensitive data including Cloudflare credentials or configuration details without requiring authentication
A user is affected if they have Hummingbird Performance plugin version 3.18.0 or earlier installed AND have Cloudflare API credentials configured in the plugin, with the vulnerable request endpoint accessible without authentication.

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 the Hummingbird Performance plugin to a version beyond 3.18.0 once available, and rotate any exposed Cloudflare API credentials immediately. Consider restricting access to the vulnerable endpoint at the web server level until the patch is applied.
