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 the WP Time Slots Booking Form WordPress plugin allows attackers to exploit incorrectly configured access control security levels. The plugin fails to properly validate user permissions before executing certain functions, enabling authenticated attackers with limited privileges to access sensitive booking data or modify configurations beyond their authorized scope.

MitigationImplement proper authorization checks on all sensitive plugin functions and enforce role-based access control (RBAC). Update to the latest plugin version if a patch is available, or restrict plugin access to administrator-level users only.

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. Confirm plugin is installed
    In WordPress admin, go to Plugins > Installed Plugins and look for 'WP Time Slots Booking Form' or check the plugin files in wp-content/plugins/ for the codepeople-post-scheduler directory (or similar plugin folder name)
    Affected if The plugin is installed and active on the WordPress site
  2. Determine installed plugin version
    In WordPress admin, go to Plugins > Installed Plugins and find the version number listed under the plugin name 'WP Time Slots Booking Form', or read the main plugin PHP file header for the Version field
    Affected if The version is lower than 1.1.83 (e.g., 1.1.82, 1.1.80, etc.)
  3. Verify access control on plugin admin pages
    Log in as a subscriber or contributor user (lowest privilege level) and attempt to access the WP Time Slots Booking Form settings page directly via URL (typically under Settings or a menu item the plugin creates), or use a browser's developer tools to inspect if adminajax.php or admin-post.php calls return successful responses when triggered by a low-privilege user
    Affected if A non-administrator user can access plugin configuration or booking data pages without being redirected or denied
  4. Check WordPress user role capabilities
    In WordPress admin under Users > Roles, or using a role management plugin, examine the capabilities assigned to subscriber, contributor, and author roles for any capabilities related to the booking plugin (such as 'manage_options', 'edit_bookings', or custom capabilities added by the plugin)
    Affected if Lower-privileged roles have been granted elevated capabilities that should be restricted to administrators only

A user is affected if the WP Time Slots Booking Form plugin version is below 1.1.83 AND non-administrator user accounts can access plugin settings, view booking data, or modify configurations without proper authorization checks.
