  2. If you cannot update right away, deactivate it until you can.
  3. Turn on auto-updates for it: Plugins → “Enable auto-updates” on its row.
  4. If you ran a vulnerable version and something looks off (spam pages, strange admins, redirects), run the free scan.

With WP-CLI: wp plugin get truebooker-appointment-booking --field=version shows what you run; wp plugin update truebooker-appointment-booking updates it.

CVE record (the advisory publisher) · score by Wordfence
Details from the advisory

The TrueBooker – Appointment Booking and Scheduler System plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.2.3. 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 email address of arbitrary user accounts, including administrators, which can be leveraged to reset the account's password and gain access to it.

Details from the advisory

The TrueBooker – Appointment Booking and Scheduler System plugin for WordPress is vulnerable to Authorization Bypass Through User-Controlled Key leading to Account Takeover in all versions up to, and including, 1.2.6. This is due to the admin_user_create_cus AJAX handler lacking any authentication or capability check before passing the attacker-supplied truebooker_wp_user_id parameter directly to wp_update_user. This makes it possible for unauthenticated attackers to overwrite the email address of any WordPress user — including an administrator — and then complete the standard WordPress lost-password flow to fully take over the targeted account.

No login needed
Range from
CVE record (the advisory publisher) · score by Wordfence
Details from the advisory

The TrueBooker plugin for WordPress is vulnerable to Account Takeover in all versions up to, and including, 1.2.6. This is due to the add_front_user_update() AJAX handler being registered for unauthenticated users and accepting an arbitrary truebooker_wp_user_id value, which is passed directly to wp_update_user() without verifying authentication or ownership. This makes it possible for unauthenticated attackers to change any WordPress user account email address, including an administrator, by submitting the target user ID and an attacker-controlled email address. An attacker can then use the native WordPress password reset flow to receive the reset link at the attacker-controlled email address and take over the account.

The TrueBooker – Appointment Booking and Scheduler System plugin for WordPress is vulnerable to account takeover via improper password reset validation in all versions up to, and including, 1.2.3. This is due to the plugin not properly validating a user's identity before resetting their password. This makes it possible for unauthenticated attackers to reset the password of arbitrary user accounts, including administrators, and gain access to those accounts.

high 7.5 CVE-2026-13161 · published 2026-07-28

Affected

Access needed (per CVSS)
No login needed
Range from
CVE record (the advisory publisher) · score by Wordfence
Details from the advisory

The TrueBooker – Appointment Booking and Scheduler System plugin for WordPress is vulnerable to generic SQL Injection via the 'alldata[truebooker_user]' parameter in all versions up to, and including, 1.2.2 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 append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. The check_ajax_referer() nonce guard does not constitute an authentication or authorization barrier because the nonce is exposed to unauthenticated visitors on TrueBooker front-end booking pages; exploitation additionally requires that the required booking fields (category, service, person, date, and time slot) be present in the alldata POST parameter so that execution reaches the vulnerable SQL query branch.
