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
The Booking Calendar Contact Form plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 1.2.60. This is due to missing authorization checks and payment verification in the `dex_bccf_check_IPN_verification` function. This makes it possible for unauthenticated attackers to arbitrarily confirm bookings and bypass payment requirements via the 'dex_bccf_ipn' parameter.

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 confidence

The Booking Calendar Contact Form WordPress plugin has a missing authorization vulnerability in the dex_bccf_check_IPN_verification function. Unauthenticated attackers can confirm arbitrary bookings and bypass payment requirements by manipulating the dex_bccf_ipn parameter, as no authorization check or payment verification is performed before processing booking confirmations.

MitigationUpdate to version 1.2.61 or later which includes proper authorization checks and payment verification. Until patched, consider disabling the plugin or implementing additional access controls at the web server level to restrict access to the vulnerable endpoint.

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 Booking Calendar Contact Form plugin is installed
    Log into WordPress admin dashboard and navigate to Plugins > Installed Plugins, or check the wp-content/plugins directory for a folder containing 'booking-calendar-contact-form' or similar naming
    Affected if The plugin is present in the WordPress installation
  2. Check installed plugin version
    In WordPress admin, find the plugin in the plugins list and note the version number displayed; alternatively, read the main plugin PHP file header for the Version field
    Affected if Version is lower than 1.2.61 (the patched version)
  3. Test unauthenticated access to IPN endpoint
    Send a crafted HTTP POST request to the site with a dex_bccf_ipn parameter (e.g., ?dex_bccf_ipn=1 or as POST data) without any authentication tokens or cookies
    Affected if The request is processed without requiring login or payment verification
  4. Verify booking confirmation accepts arbitrary IDs
    Attempt to confirm a booking by sending a request with the dex_bccf_ipn parameter and a booking ID value, observing whether the system confirms a booking without validating ownership or payment status
    Affected if Arbitrary booking IDs can be confirmed without authorization or payment proof

If the Booking Calendar Contact Form plugin is installed at a version below 1.2.61 and the IPN endpoint accepts unauthenticated requests with the dex_bccf_ipn parameter, the environment is affected by this vulnerability.
