Technical Description
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.
Potential Impact
If exploited, this high-severity vulnerability could allow an attacker to compromise sensitive data confidentiality. Organizations running affected software should treat this as a priority remediation item.
Recommended Action
No official patch is available yet. Until one is released:
- Monitor the official NVD page and vendor channels for patch announcements.
- Restrict access to the affected system or service where possible.
- Apply network-level mitigations such as firewall rules or WAF policies.
- Enable logging and alerting for anomalous activity related to this vulnerability.
- Review your incident response plan in case of active exploitation.
