CVE-2026-94432, 2 Oct 2026
The Appointment Booking Plugin - LatePoint | Calendar & Scheduling for WordPress plugin for WordPress is vulnerable to Insecure Direct Object Reference in versions up to, and including, 5.7.1 via the OsPaypalConnectController::create_order_for_transaction() action registered as a public (unauthenticated) route through wp_ajax_nopriv_latepoint_route_call. The handler loads an OsInvoiceModel by a sequential integer 'invoice_id' with no access-key/UUID or ownership check (the sibling Stripe and Razorpay handlers require a 128-bit access-key UUID via OsInvoicesHelper::get_invoice_by_key), and then calls OsTransactionIntentHelper::create_or_update_transaction_intent() which persists a transaction intent tied to the target invoice's customer_id, order_id and charge_amount and regenerates its intent_key before the PayPal-configured guard is reached. This makes it possible for unauthenticated attackers to enumerate invoices belonging to arbitrary customers, create unauthorized transaction-intent rows linked to another customer's data, and overwrite the intent_key of any in-flight NEW-status transaction intent - invalidating the intent_key that legitimate Stripe/Razorpay flows are waiting on and breaking payment webhooks for those customers. CVE record
CVE-2026-92966, 1 Oct 2026
The The Appointment Booking Plugin - LatePoint | Calendar & Scheduling for WordPress plugin for WordPress is vulnerable to arbitrary shortcode execution in all versions up to, and including, 5.7.0. This is due to the software allowing users to execute an action that does not properly validate a value before running do_shortcode. This makes it possible for unauthenticated attackers to execute arbitrary shortcodes. The payload is planted during the unauthenticated booking flow and triggered when the Customer Cabinet block rendered by render_customer_dashboard() outputs the stored name into the content stream, where WordPress core's do_shortcode filter at priority 11 re-parses and executes it. CVE record
CVE-2026-13471, 18 Sep 2026
The LatePoint - Calendar Booking Plugin for Appointments and Events plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 5.6.3 via the LatePointAbilityDeleteBooking::execute due to missing validation on a user controlled key. This makes it possible for attackers, with LatePoint Agent-level access and above, to read bookings and customer PII (full name, email, phone, and notes) assigned to other LatePoint agents, and delete arbitrary bookings by supplying any booking ID. This vulnerability is only exploitable when an administrator has enabled the Abilities API toggles (latepoint_abilities_api, latepoint_abilities_api_delete, and/or latepoint_abilities_api_edit) in the plugin settings. CVE record
CVE-2026-18441, 18 Sep 2026
The Appointment Booking Plugin - LatePoint | Calendar & Scheduling for WordPress plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 5.6.9 via the set_customer_object due to missing validation on a user controlled key. This makes it possible for unauthenticated attackers to enumerate arbitrary customer records and disclose personally identifiable information - including first name, last name, email address, and phone number - by iterating the customer[id] parameter. This issue is exploitable only when the site is configured with customer authentication disabled (guest checkout enabled). CVE record
CVE-2026-5391, 6 Aug 2026
The LatePoint plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'btn_wrapper_classes' attribute of the 'latepoint_resources' shortcode in all versions up to, and including, 5.3.2. This is due to insufficient input sanitization and output escaping in the 'locations' branch of the 'shortcode_latepoint_resources' function. This makes it possible for authenticated attackers, with contributor level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. CVE record
CVE-2026-15250, 30 Jul 2026
The Appointment Booking Plugin WordPress plugin before 5.6.8 does not restrict which booking fields an unauthenticated visitor can set through its public booking funnel, allowing an unauthenticated user to assign a privileged booking field such as the approval status and thereby bypass the site's booking approval workflow. CVE record
CVE-2026-11866, 16 Jul 2026
The Appointment Booking Plugin WordPress plugin before 5.6.3 does not validate a CSRF nonce on several state-changing actions handled by its central request dispatcher, allowing attackers to perform privileged actions, such as overwriting the booking-form configuration or disconnecting the connected payment gateway, via Cross-Site Request Forgery against a logged-in administrator. CVE record
CVE-2026-5356, 8 Jul 2026
The LatePoint - Calendar Booking Plugin for Appointments and Events plugin for WordPress is vulnerable to Improper Input Validation in all versions up to, and including, 5.4.0. This is due to the plugin's Stripe Connect payment processor accepting a client-supplied PaymentIntent ID. This makes it possible for unauthenticated attackers to pay an arbitrary amount by supplying a previously succeeded PaymentIntent token. CVE record
CVE-2026-11398, 3 Jul 2026
The LatePoint - Calendar Booking Plugin for Appointments and Events plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 5.6.1. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to modify the personally identifiable information (first name, last name, phone number, and notes) of any existing customer record, including those linked to administrator accounts, by submitting the booking form with a known customer's email address. Exploitation requires the plugin to be configured with guest bookings enabled (is_customer_auth_disabled() returning true), which is necessary for the vulnerable unauthenticated code path in process_step_customer() to be reached. CVE record
CVE-2026-12657, 2 Jul 2026
The LatePoint - Calendar Booking Plugin for Appointments and Events plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 5.6.2 via the 'service_id' parameter due to missing validation on a user controlled key. This makes it possible for unauthenticated attackers to create approved bookings against services explicitly restricted to admins and agents, consuming restricted appointment capacity and triggering unauthorized bookings for admin/agent-only services. The bypass works via both the params[booking][service_id] parameter in steps__load_step and the presets[selected_service] parameter in steps__start, both of which are publicly accessible without authentication. CVE record
CVE-2026-13228, 1 Jul 2026
The LatePoint - Calendar Booking Plugin for Appointments and Events plugin for WordPress is vulnerable to Privilege Escalation to Administrator in versions up to, and including, 5.6.3 This is due to an Insecure Direct Object Reference (IDOR) in the create_or_update() function of OsOrdersController, which allows an authenticated Agent to supply an arbitrary order[customer_id] and overwrite any LatePoint customer's email field (including one linked to a WordPress Administrator's account) through the public-scope customer set_data() call, combined with a missing role verification in OsAuthHelper::authorize_customer() which logs in the linked WordPress user without checking its role. This makes it possible for authenticated attackers, with custom (Agent)-level access and above, to elevate their privileges to Administrator. CVE record
CVE-2026-8176, 16 Jun 2026
The LatePoint - Calendar Booking Plugin for Appointments and Events plugin for WordPress is vulnerable to Privilege Escalation to Administrator in versions up to, and including, 5.5.1. The plugin chains three independent flaws that together allow an authenticated Agent (Agent+) to overwrite a WordPress Administrator's password without ever invoking an Administrator-only API. This makes it possible for authenticated attackers, with Agent access and above, to elevate their privileges to Administrator. CVE record
CVE-2026-9719, 6 Jun 2026
The LatePoint - Calendar Booking Plugin for Appointments and Events plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 5.6.0. This is due to missing or incorrect nonce validation on the change_status function. This makes it possible for unauthenticated attackers to change the status of arbitrary invoices - including marking unpaid invoices as paid - without administrator consent via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. CVE record
CVE-2026-5365, 14 May 2026
The LatePoint plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to and including 5.3.2. This is due to missing nonce verification on the request_cancellation() function. This makes it possible for unauthenticated attackers to cancel a logged-in customer's bookings via a forged request, granted they can trick the customer into performing an action such as clicking on a link. CVE record
CVE-2026-7652, 9 May 2026
The LatePoint plugin for WordPress is vulnerable to Account Takeover via Weak Password Recovery Mechanism in the unauthenticated guest booking flow in versions up to, and including, 5.5.0 This is due to the save_connected_wordpress_user() function propagating a LatePoint customer's email address to its linked WordPress user account via wp_update_user() without any ownership verification, combined with the guest booking flow's ability to overwrite an existing customer's email through phone-based merge without authentication. This makes it possible for unauthenticated attackers to overwrite the email address of a non-super-admin WordPress user account that is not yet linked to a LatePoint customer, enabling full account takeover by subsequently triggering the standard WordPress password-reset flow to the attacker-controlled address granted the plugin is configured with WordPress user integration enabled, phone-based contact merging, and customer authentication disabled. Administrator accounts on single-site installs are not affected. CVE record
CVE-2026-7332, 6 May 2026
The LatePoint - Calendar Booking Plugin for Appointments and Events plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'booking_form_page_url' parameter in all versions up to, and including, 5.5.0 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The malicious activity log entry is written to the database even when Stripe is not configured, because the latepoint_order_intent_created action hook fires before the Stripe Connect account ID is validated, meaning a fully functional Stripe integration is not required for exploitation. CVE record
CVE-2026-7457, 6 May 2026
The LatePoint plugin for WordPress is vulnerable to Stored Cross-Site Scripting in all versions up to and including 5.5.0. This is due to insufficient input sanitization on the customer cabinet profile update endpoint - where raw POST parameters (first_name, last_name, phone, notes) bypass sanitization because OsCustomerModel does not override params_to_sanitize(), causing set_data() to store unsanitized values verbatim in the database - combined with insufficient output escaping in generate_preview(), which injects those stored values into notification template HTML via str_replace() without any esc_html() call before echoing the result. This makes it possible for authenticated attackers with customer-level access or above to inject arbitrary web scripts into the admin notification preview panel that execute in an administrator's or agent's browser whenever a notification template referencing customer variables such as {{customer_full_name}}, {{customer_first_name}}, {{customer_last_name}}, {{customer_phone}}, or {{customer_notes}} is previewed. CVE record
CVE-2026-6741, 27 Apr 2026
The LatePoint - Calendar Booking Plugin for Appointments and Events plugin for WordPress is vulnerable to Privilege Escalation in versions up to and including 5.4.1. This is due to a missing authorization check in the execute() method of the connect-customer-to-wp-user ability, which only requires the customer__edit capability granted to the latepoint_agent role by default, without verifying whether the target WordPress user ID belongs to a privileged account. This makes it possible for authenticated attackers with the latepoint_agent role to link any LatePoint customer record to an administrator's WordPress account and subsequently reset the administrator's password via the normal customer password-reset flow, resulting in full site takeover. CVE record
CVE-2026-5234, 17 Apr 2026
The LatePoint plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 5.3.2. The vulnerability exists because the OsStripeConnectController::create_payment_intent_for_transaction action is registered as a public action (no authentication required) and loads invoices by sequential integer invoice_id without any access_key or ownership verification. This is in contrast to other invoice-related actions (view_by_key, payment_form, summary_before_payment) in OsInvoicesController which properly require a cryptographic UUID access_key. This makes it possible for unauthenticated attackers to enumerate valid invoice IDs via an error message oracle, create unauthorized transaction intent records in the database containing sensitive financial data (invoice_id, order_id, customer_id, charge_amount), and on sites with Stripe Connect configured, the response also leaks Stripe payment_intent_client_secret tokens, transaction_intent_key values, and payment amounts for any invoice. CVE record
CVE-2026-4785, 8 Apr 2026
The LatePoint - Calendar Booking Plugin for Appointments and Events plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'button_caption' parameter in the [latepoint_resources] shortcode in versions up to and including 5.3.0. This is due to insufficient output escaping when the 'items' parameter is set to 'bundles'. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. CVE record
CVE-2026-2324, 11 Mar 2026
The LatePoint - Calendar Booking Plugin for Appointments and Events plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 5.2.7. This is due to missing or incorrect nonce validation on the reload_preview() function. This makes it possible for unauthenticated attackers to update settings and inject malicious web scripts via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. CVE record
CVE-2025-14873, 14 Feb 2026
The LatePoint - Calendar Booking Plugin for Appointments and Events plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 5.2.5. This is due to the 'call_by_route_name' function in the routing layer only validating user capabilities without enforcing nonce verification. This makes it possible for unauthenticated attackers to perform multiple administrative actions via forged requests granted they can trick a site administrator into performing an action such as clicking on a link. CVE record
CVE-2026-1537, 12 Feb 2026
The LatePoint - Calendar Booking Plugin for Appointments and Events plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the load_step() function in all versions up to, and including, 5.2.6. This makes it possible for unauthenticated attackers to view booking information including customer names, email addresses, phone numbers, appointment times, and service details. CVE record
CVE-2026-0617, 3 Feb 2026
The LatePoint - Calendar Booking Plugin for Appointments and Events plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the customer profile fields in all versions up to, and including, 5.2.5 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever an administrator views the customer's activity history. CVE record
CVE-2025-7038, 30 Sep 2025
The LatePoint plugin for WordPress is vulnerable to Authentication Bypass due to insufficient identity verification within the steps__load_step route of the latepoint_route_call AJAX endpoint in all versions up to, and including, 5.1.94. The endpoint reads the client-supplied customer email and related customer fields before invoking the internal login handler without verifying login status, capability checks, or a valid AJAX nonce. This makes it possible for unauthenticated attackers to log into any customer’s account. CVE record
CVE-2025-7052, 30 Sep 2025
The LatePoint plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 5.1.94. This is due to missing nonce validation on the change_password() function of its customer_cabinet__change_password AJAX route. The plugin hooks this endpoint via wp_ajax and wp_ajax_nopriv but does not verify a nonce or user capability before resetting the user’s password. This makes it possible for unauthenticated attackers who trick a logged-in customer (or, with “WP users as customers” enabled, an administrator) into visiting a malicious link to take over their account. CVE record
CVE-2025-6815, 30 Sep 2025
The LatePoint - Calendar Booking Plugin for Appointments and Events plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘service[name]’ parameter in all versions up to, and including, 5.1.94 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level access, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled. CVE record
CVE-2025-6941, 30 Sep 2025
The LatePoint - Calendar Booking Plugin for Appointments and Events plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'id' parameter of the 'latepoint_resources' shortcode in all versions up to, and including, 5.1.94 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. CVE record
CVE-2025-3769, 14 May 2025
The LatePoint - Calendar Booking Plugin for Appointments and Events plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 5.1.92 via the 'view_booking_summary_in_lightbox' due to missing validation on a user controlled key. This makes it possible for unauthenticated attackers to retrieve appointment details such as customer names and email addresses. CVE record
CVE-2024-8911, 8 Oct 2024
The LatePoint plugin for WordPress is vulnerable to Arbitrary User Password Change via SQL Injection in versions up to, and including, 5.0.11. This is due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to change user passwords and potentially take over administrator accounts. Note that changing a WordPress user's password is only possible if the "Use WordPress users as customers" setting is enabled, which is disabled by default. Without this setting enabled, only the passwords of plugin customers, which are stored and managed in a separate database table, can be modified. CVE record
CVE-2024-8943, 8 Oct 2024
The LatePoint plugin for WordPress is vulnerable to authentication bypass in versions up to, and including, 5.0.12. This is due to insufficient verification on the user being supplied during the booking customer step. This makes it possible for unauthenticated attackers to log in as any existing user on the site, such as an administrator, if they have access to the user id. Note that logging in as a WordPress user is only possible if the "Use WordPress users as customers" setting is enabled, which is disabled by default. The vulnerability is partially patched in version 5.0.12 and fully patched in version 5.0.13. CVE record
CVE-2024-2472, 14 Jun 2024
The LatePoint Plugin plugin for WordPress is vulnerable to unauthorized access of data and modification of data due to a missing capability check on the 'start_or_use_session_for_customer' function in all versions up to and including 4.9.9. This makes it possible for unauthenticated attackers to view other customer's cabinets, including the ability to view PII such as email addresses and to change their LatePoint user password, which may or may not be associated with a WordPress account. CVE record
