Oct 10, 2026Booking Calendar: Sensitive Information ExposureCVE-2026-18496 · affects up to 11.4.3 · reported by WordfenceMedium 5.3
The Booking Calendar plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 11.4.3 via the wpbc_is_show_popover_in_flex_timeline() function. This makes it possible for unauthenticated attackers to extract sensitive data including names, email addresses, and phone numbers of customers who have made bookings.
Oct 8, 2026Booking Calendar: Does not adequately restrictCVE-2026-105195 · fixed in 11.8.3 · reported by WPScanLow 2.7
The Booking Calendar WordPress plugin before 11.8.3 does not adequately restrict which options a lower-privileged user can load through one of its settings handlers, allowing users with the Editor role and above to disclose the values of arbitrary WordPress options, including core site configuration.
Oct 8, 2026Booking Calendar: Does not generate its per-booking access hashes with sufficient entropyCVE-2026-105193 · fixed in 11.8 · reported by WPScanMedium 4.8
The Booking Calendar WordPress plugin before 11.8 does not generate its per-booking access hashes with sufficient entropy, deriving each from a low-entropy time-seeded value, which can allow unauthenticated attackers who are able to determine a booking's creation time to predict the hash and then read that booking's personal data or modify the booking in place.
Oct 2, 2026Booking Calendar: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')CVE-2026-39601 · affects up to 11.8.4 · reported by PatchstackLow 3.7

Sep 22, 2026Booking Calendar: Reflected Cross-Site ScriptingCVE-2026-93655 · affects up to 11.8.3 · reported by WordfenceMedium 6.1
The Booking Calendar plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'wpbc_auto_fill' parameter in all versions up to, and including, 11.8.3 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

Sep 18, 2026Booking Calendar: Privilege EscalationCVE-2026-92619 · affects up to 11.8.2 · reported by WordfenceHigh 7.2
The Booking Calendar plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 11.8.2 via the `wpbc_ajax_option_save` AJAX action. The vulnerability exists because the `handle_ajax_save()` function applies per-option safeguards only to names explicitly registered via `register_option_policy()`, causing `get_option_policy()` to return an empty policy — bypassing all can_save, force_mode, and allowed_keys checks — for any unregistered option name, including core WordPress options, while an attacker-controlled `data_name` parameter passes through `sanitize_key()` and is written directly to `update_option()` without restriction. This makes it possible for authenticated attackers with Editor-level access and above to escalate their privileges to Administrator by writing core WordPress options such as `default_role=administrator` and `users_can_register=1`, then self-registering a new Administrator account. The nonce check does not meaningfully restrict this attack, as both the nonce value and nonce action are attacker-supplied POST parameters, and a valid nonce is trivially obtainable via `admin-ajax.php?action=rest-nonce`.

Sep 18, 2026Booking Calendar: Reflected Cross-Site ScriptingCVE-2026-92561 · affects up to 11.8.2 · reported by WordfenceMedium 6.1
The Booking Calendar plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'options' parameter in all versions up to, and including, 11.8.2 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. The nonce check is bypassed by default because the 'booking_is_nonce_at_front_end' option ships disabled, allowing unauthenticated requests to reach the vulnerable sink without any verification.

Feb 18, 2026Booking Calendar: Insecure Direct Object ReferenceCVE-2026-2230 · affects up to 10.14.14 · reported by WordfenceMedium 4.3
The Booking Calendar plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 10.14.14 via the handle_ajax_save function due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with Subscriber-level access and above, and booking permissions granted by an Administrator, to modify other users' plugin settings, such as booking calendar display options, which can disrupt the booking calendar functionality for the targeted user.

Jan 31, 2026Booking Calendar: Unauthorized access of dataCVE-2026-1431 · affects up to 10.14.13 · reported by WordfenceMedium 5.3
The Booking Calendar plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the wpbc_ajax_WPBC_FLEXTIMELINE_NAV() function in all versions up to, and including, 10.14.13.

Jan 9, 2026Booking Calendar: Sensitive Information ExposureCVE-2025-14146 · affects up to 10.14.10 · reported by WordfenceMedium 5.3
The Booking Calendar plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 10.14.10 via the `WPBC_FLEXTIMELINE_NAV` AJAX action. This is due to the nonce verification being conditionally disabled by default (`booking_is_nonce_at_front_end` option is `'Off'` by default). When the `booking_is_show_popover_in_timeline_front_end` option is enabled (which is the default in demo installations and can be enabled by administrators), it is possible for unauthenticated attackers to extract sensitive booking data including customer names, email addresses, phone numbers, and booking details.
