The WP Travel plugin for WordPress contains a SQL Injection vulnerability (CVE-2024-12067) in the 'booking_itinerary' parameter of the 'wptravel_get_booking_data' function. This occurs due to improper neutralization of special elements in SQL commands, allowing authenticated users with Subscriber-level privileges or higher to append malicious SQL queries. This can lead to unauthorized disclosure of sensitive database information. The vulnerability affects all versions up to and including 10.0.0. The CVSS 3.1 base score is 6.5, indicating a medium severity with network attack vector, low attack complexity, and no user interaction required. No patch or official vendor advisory is currently available.

An authenticated attacker with Subscriber-level access or higher can exploit this vulnerability to perform SQL Injection attacks, potentially extracting sensitive information from the database. The vulnerability does not affect integrity or availability directly but compromises confidentiality. The medium CVSS score reflects the moderate risk due to required authentication and the ability to access sensitive data.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict Subscriber-level access to trusted users only and monitor for suspicious activity related to the 'booking_itinerary' parameter. Avoid exposing the vulnerable plugin on publicly accessible sites if possible. Follow vendor channels for updates and apply patches promptly once available.
