CVE-2026-11802
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 FoodBook Lite - Online Food Ordering System plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 1.5.6. The registration() function, accessible via the wp_ajax_nopriv_registration_action AJAX action, lacks any nonce verification or capability check, and does not check the WordPress users_can_register option before calling wp_insert_user(). This makes it possible for unauthenticated attackers to create new user accounts with the 'customer' role and receive authentication cookies, even when the site administrator has explicitly disabled user registration.
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 FoodBook Lite WordPress plugin's registration() function is accessible to unauthenticated users via the wp_ajax_nopriv_registration_action AJAX action without any nonce verification, capability checks, or validation of the WordPress users_can_register setting. This allows attackers to arbitrarily create user accounts with the customer role and obtain authentication cookies, even when registration is disabled site-wide.

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.
-
Identify FoodBook Lite plugin versionNavigate to Plugins > Installed Plugins in WordPress admin dashboard and locate FoodBook Lite, or inspect the plugin's main PHP file for the 'Version' header commentAffected if Version is present and is lower than 1.5.7
-
Verify AJAX action hook existsInspect the plugin PHP files for add_action('wp_ajax_nopriv_registration_action', ...) or add_action('wp_ajax_registration_action', ...) declarationsAffected if The registration_action AJAX hook is registered without capability checks or nonce verification
-
Check WordPress user registration settingGo to Settings > General in WordPress admin and examine the 'Anyone can register' checkbox under MembershipAffected if Registration is disabled site-wide but the plugin would still allow account creation (confirms the vulnerability condition)
-
Confirm version is in affected rangeCompare your installed FoodBook Lite version number to the fixed version 1.5.7Affected if Installed version is below 1.5.7 and any of the above conditions are true
A user is affected if FoodBook Lite version is below 1.5.7 and the plugin's registration AJAX action is accessible to unauthenticated users without proper authorization checks.

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 1.5.7 or later which includes proper authorization checks, or implement WordPress security best practices by adding nonce verification and capability checks (manage_options) to AJAX actions, plus validate the users_can_register option before allowing user creation.
