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

A missing authorization vulnerability in the Webba Booking WordPress plugin (webba-booking-lite) allows attackers to exploit incorrectly configured access control security levels, potentially enabling unauthorized access to booking functionalities or administrative actions that should require proper authentication and authorization checks.

MitigationUpgrade to a version beyond 5.1.20 that contains proper authorization controls, or implement and enforce access control validation at all affected endpoints within 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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed Webba Booking version
    Log into WordPress admin, go to Plugins > Installed Plugins, locate 'Webba Booking Lite' or 'Webba Booking', and note the version number displayed. Alternatively, check the plugin's main PHP file (usually in wp-content/plugins/webba-booking-lite/ or webba-booking/) for the 'Version' header in the plugin comment block.
    Affected if The installed version is 5.1.20 or any earlier version (e.g., 5.1.19, 5.1.18, etc.)
  2. Confirm plugin is active and accessible
    Verify the Webba Booking plugin is installed and activated in WordPress admin. Check if the booking functionality is publicly accessible by visiting any booking page or endpoint that uses the plugin (often contains '/booking/' in the URL path).
    Affected if The plugin is active and its booking functionality is exposed via frontend pages or public URLs without requiring login.
  3. Identify exposed administrative endpoints
    Inspect the plugin's AJAX handlers and admin pages. Check for URLs like /wp-admin/admin-ajax.php?action=webba_... or /wp-admin/admin.php?page=webba-booking... that may handle booking management, appointment modifications, or user data. Use a network proxy or check the plugin source code for action hooks (add_action) that handle request processing.
    Affected if The plugin exposes administrative action endpoints (create, read, update, delete operations on bookings, services, or settings) that do not include current_user_can() or similar capability checks before processing requests.
  4. Test for authorization bypass on booking actions
    Submit a crafted request to a known plugin endpoint (e.g., AJAX actions for creating, updating, or deleting bookings) while logged out or as a low-privilege user. Observe whether the request is processed without returning a permission denied error or requiring authentication.
    Affected if Requests to booking management endpoints succeed without proper authentication or authorization validation, allowing unauthorized manipulation of bookings or plugin settings.

You are affected if the Webba Booking plugin version is 5.1.20 or earlier AND the plugin exposes booking or administrative functionality that can be accessed or manipulated without proper authorization checks.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade to a version beyond 5.1.20 that contains proper authorization controls, or implement and enforce access control validation at all affected endpoints within the plugin.

Recommended fix Moderate confidence

Latest version of Webba Booking Lite (greater than 5.1.20)

  1. 1. Back up your WordPress site before performing any updates
  2. 2. Navigate to Plugins > Installed Plugins in your WordPress admin dashboard
  3. 3. Locate Webba Booking Lite in the plugin list
  4. 4. If an update is available, click 'Update Now' to install the latest version
  5. 5. Alternatively, download the latest version from the official WordPress plugin repository or vendor website
  6. 6. After updating, verify that the authorization controls are functioning correctly by testing access to previously protected functionality
  7. 7. Confirm the updated version number is greater than 5.1.20
