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
Missing Authorization vulnerability in Arraytics WPCafe wp-cafe allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects WPCafe: from n/a through <= 3.0.7.

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

Missing Authorization vulnerability in WPCafe WordPress plugin allows attackers to access functionality or data without proper authentication/authorization checks. The vulnerability stems from incorrectly configured access control security levels, likely due to missing capability checks or nonce validations on sensitive operations.

MitigationUpdate WPCafe plugin to the latest version when available. Until then, restrict access to wp-admin paths, disable unnecessary endpoints, and monitor for suspicious access patterns.

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 WPCafe plugin is installed
    Navigate to WordPress admin dashboard > Plugins and confirm WPCafe is listed, or inspect the file /wp-content/plugins/wp-cafe/core/Plugin.php (or main plugin file) to read the version from the plugin header comment
    Affected if WPCafe plugin is not installed or not present on the system
  2. Identify installed WPCafe version
    Check the plugin version number in the plugin header (Plugin Name, Version fields) or query the database wp_options table for the option_name containing 'wpcafe' version info
    Affected if The installed version is lower than the patched version (compare against official WPCafe release notes or security advisory)
  3. Inspect AJAX endpoints for missing capability checks
    Review PHP files in /wp-content/plugins/wp-cafe/ for AJAX handlers (wp_ajax_ and wp_ajax_nopriv_ hooks). Examine whether these handlers call current_user_can() or proper authorization checks before executing sensitive operations
    Affected if AJAX endpoints accessible to unauthenticated users (wp_ajax_nopriv_) lack capability checks or nonce validation
  4. Check admin action handlers for missing authorization
    Examine PHP files handling admin actions (form submissions, settings changes, data exports) for the presence of nonce verification (wp_verify_nonce or check_admin_referer) and capability checks (current_user_can) before processing requests
    Affected if Admin action handlers process requests without verifying user capabilities or validating nonces
  5. Test sensitive endpoints without authentication
    Use a browser or HTTP client to access known WPCafe endpoints (e.g., frontend booking forms, reservation submissions, calendar exports) while logged out, observing whether data is returned or actions execute without requiring login
    Affected if Sensitive operations execute or return protected data when accessed without authentication

If WPCafe is installed and the installed version is older than the patched version, or if sensitive endpoints respond without authentication, the environment is likely affected by CVE-2026-27071.
