MITRE ATT&CK
2 techniques across 2 tactics: Initial Access, Persistence The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Exploitation Conditions | Exploitation requires that the attacker submits a POST request with the 'alldata[truebooker_user]' parameter set to an SQL injection payload and the mandatory booking fields (category, service, person, date, time slot) present in the alldata array, so that execution reaches the vulnerable SQL branch. The nonce can be obtained by any unauthenticated visitor from the front-end booking form, so no authentication is needed. No other special configuration is necessary; the vulnerability exists in the default plugin setup. |
| Impact | CVSS 3.1 base score 7.5 (High) with a network attack vector, low complexity, no privileges required, and no user interaction, leading to high confidentiality impact only. No EPSS score is available to estimate exploitation probability, and the vulnerability is not listed in CISA KEV, indicating no known active exploitation at this time. However, the low attack complexity and the public exposure of the required nonce on front-end pages make this a realistic threat for data theft, especially on sites where the plugin is active and booking pages are publicly accessible. |
| Exploit ScenarioDerived | An attacker extracts the nonce from a public TrueBooker booking page, then sends a crafted POST request to wp-admin/admin-ajax.php containing the 'alldata[truebooker_user]' parameter with an SQL injection payload and all required booking fields (category, service, person, date, time slot). The vulnerable code constructs an unsafe SQL query, allowing the attacker to retrieve sensitive database contents such as user credentials or configuration data. |

Alert meAnalysisAIv1 – Jul 28, 2026
Unauthenticated SQL injection in the TrueBooker WordPress plugin allows remote attackers to extract sensitive database information. The vulnerability resides in the 'alldata[truebooker_user]' parameter and affects versions up to and including 1.2.2. Although a nonce is used, it is exposed on front-end booking pages, enabling unauthenticated exploitation if the required booking fields are present.
RemediationAI
Upgrade the TrueBooker plugin to a version newer than 1.2.2. A fix has been committed to the plugin's trunk, as shown in the changeset comparison between version 1.2.2 and the development trunk. Until an official patched release is published, monitor the plugin's WordPress.org page for an update. If immediate update is not feasible, consider temporarily disabling the plugin; blocking access to booking pages may break functionality. No specific later release version is confirmed from the provided references.

Technical ContextAI · show details
The vulnerability is in the TrueBooker - Appointment Booking and Scheduler System plugin for WordPress, specifically in the file main/function_ajax.php, where user-supplied data from the 'alldata[truebooker_user]' parameter is incorporated into an SQL query without sufficient escaping or parameterization. This falls under CWE-89 (SQL Injection). The affected product is the WordPress plugin 'truebooker-appointment-booking', version 1.2.2 and earlier, as shown by the plugin's SVN repository references.

DescriptionCVE.org
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.
