Detailsinfo

A vulnerability, which was classified as critical, was found in themefic Tourfic Plugin up to 2.22.7 on WordPress. Affected is an unknown code of the component AJAX Handler. The manipulation of the argument post_id with an unknown input leads to a sql injection vulnerability. CWE is classifying the issue as CWE-89. The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

The Tourfic – AI Powered Travel Booking, Hotel Booking & Car Rental WordPress Plugin plugin for WordPress is vulnerable to generic SQL Injection via the 'post_id' parameter in all versions up to, and including, 2.22.7 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 AJAX handler is registered for unauthenticated users via wp_ajax_nopriv_tf_room_availability, and the required nonce is emitted on the public single-hotel page template, allowing unauthenticated attackers to freely obtain a valid nonce and reach the vulnerable code path.

The weakness was disclosed by PRISM. The advisory is shared for download at wordfence.com. This vulnerability is traded as CVE-2026-12937 since 06/22/2026. The exploitability is told to be easy.
