What the vulnerability does

01Description

The MotoPress Hotel Booking plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 6.0.1. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to overwrite or delete the internal notes (_mphb_booking_internal_notes) of any booking by supplying an arbitrary booking ID. The nonce for this action is output in the HTML source of every public page through wp_localize_script (MPHB._data.nonces), so any unauthenticated visitor can obtain a valid nonce and perform the action without any account or prior interaction.

Explanation of Vulnerability in Simple Terms

02Summary

MotoPress Hotel Booking versions up to 6.0.1 lack proper authorization checks, allowing unauthenticated attackers to modify data on the site. The vulnerability requires no user interaction and can be exploited over the network. Site administrators should update to a version newer than 6.0.1 to remediate this issue.
