Oct 28, 2026Appointment Booking Calendar: Stored Cross-Site ScriptingCVE-2026-111727 · affects up to 1.4.05 · reported by WordfenceMedium 6.4
The Appointment Booking Calendar plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'vs_text_submitbtn' parameter in all versions up to, and including, 1.4.05 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This requires the attacker to be assigned as a calendar owner, a per-user grant that any administrator can extend to users as low as Subscriber level through the plugin's calendar list screen. Exploitation by attackers with subscriber-level access and above requires that an administrator has assigned the attacker's account as owner (`conwer`) of a calendar via the plugin's calendar list screen; the plugin's UI lists all registered users regardless of role, so a Subscriber can be assigned. On a default installation, where that is not configured, the vulnerability requires attackers with editor-level access and above.

Jun 18, 2026Appointment Booking Calendar: Sensitive Information ExposureCVE-2026-12111 · affects up to 1.4.01 · reported by WordfenceMedium 4.3
The Appointment Booking Calendar plugin for WordPress is vulnerable to Sensitive Information Exposure in versions up to, and including, 1.4.01. This is due to insufficient authorization and missing per-calendar ownership checks in the cpabc_appointments_calendar_load2() function, which is reachable via the cpabc_calendar_load2=1 query parameter in wp-admin and only checks is_admin() && current_user_can('edit_posts'), a capability available to Contributor-level users and above. This makes it possible for authenticated attackers with Contributor-level access and above to supply an arbitrary calendar ID via the id parameter and extract customer booking information, including email addresses, names, phone numbers, booking times, and comments, from any calendar managed by the plugin.

Nov 22, 2025Appointment Booking Calendar: Missing AuthorizationCVE-2025-13317 · affects up to 1.3.96 · reported by WordfenceMedium 5.3
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.
