The CP Contact Form with PayPal plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 1.3.56. This is due to the plugin exposing an unauthenticated IPN-like endpoint (via the 'cp_contactformpp_ipncheck' query parameter) that processes payment confirmations without any authentication, nonce verification, or PayPal IPN signature validation. This makes it possible for unauthenticated attackers to mark form submissions as paid without making actual payments by sending forged payment notification requests with arbitrary POST data (payment_status, txn_id, payer_email).

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.

The Appointment Booking Calendar plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 1.3.96. This is due to the plugin exposing an unauthenticated booking processing endpoint (cpabc_appointments_check_IPN_verification) that trusts attacker-supplied payment notifications without verifying their origin, authenticity, or requiring proper authorization checks. This makes it possible for unauthenticated attackers to arbitrarily confirm bookings and insert them into the live calendar via the 'cpabc_ipncheck' parameter, triggering administrative and customer notification emails and disrupting operations.

The Subscriptions & Memberships for PayPal plugin for WordPress is vulnerable to fake payment creation in all versions up to, and including, 1.1.7. This is due to the plugin not properly verifying the authenticity of an IPN request. This makes it possible for unauthenticated attackers to create fake payment entries that have not actually occurred.

The Booking Plugin for WordPress Appointments – Time Slot plugin for WordPress is vulnerable to unauthorized email sending in versions up to, and including, 1.4.7 due to missing validation on the tslot_appt_email AJAX action. This makes it possible for unauthenticated attackers to send appointment notification emails to arbitrary recipients with attacker-controlled text content in certain email fields, potentially enabling the site to be abused for phishing campaigns or spam distribution.

The Booking Calendar | Appointment Booking | Bookit plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the '/wp-json/bookit/v1/commerce/stripe/return' REST API Endpoint in all versions up to, and including, 2.5.0. This makes it possible for unauthenticated attackers to connect their Stripe account and receive payments.

The Simple Downloads List plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'wp_ajax_neofix_sdl_edit' AJAX endpoint along with many others in all versions up to, and including, 1.4.3. This makes it possible for authenticated attackers, with Subscriber-level access and above, to alter many of the plugin's settings/downloads and inject malicious web scripts.

The The Events Calendar plugin for WordPress is vulnerable to unauthorized access due to a missing capability check on the 'tec_qr_code_modal' AJAX endpoint in all versions up to, and including, 6.15.9. This makes it possible for authenticated attackers, with Subscriber-level access and above, to view draft event names and generate/view QR codes for them.

ProcessWire CMS 3.0.246 allows a low-privileged user with lang-edit to upload a crafted ZIP to Language Support that is auto-extracted without limits prior to validation, enabling resource-exhaustion Denial of Service.
