    Five Star Restaurant Reservations <= 2.7.16 - Unauthenticated Payment Bypass via PHP Type Juggling in 'payment_id' Parameter
    Summary
    The Five Star Restaurant Reservations plugin for WordPress is vulnerable to a payment bypass via PHP type juggling in versions up to, and including, 2.7.16 This is due to the valid_payment() function using a PHP loose comparison (==) between the attacker-controlled payment_id POST parameter and the booking's stripe_payment_intent_id property. When an unauthenticated attacker submits a request to the nopriv AJAX handler rtb_stripe_pmt_succeed before the Stripe payment intent has been created for a booking (i.e., before the JavaScript-triggered create_stripe_pmtIntnt() call has stored an intent ID in post meta), the stripe_payment_intent_id property on the booking object remains null. The comparison sanitize_text_field('') == null evaluates to TRUE in PHP loose comparison, causing the payment verification check to pass with zero actual payment. This makes it possible for unauthenticated attackers to mark any existing payment_pending booking as paid without completing a Stripe payment by submitting an empty payment_id parameter.

    Title
    Five Star Restaurant Reservations – WordPress Booking Plugin <= 2.7.5 - Unauthenticated Stored Cross-Site Scripting
    Summary
    The Five Star Restaurant Reservations – WordPress Booking Plugin plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'rtb-name' parameter in all versions up to, and including, 2.7.5 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

When an unauthenticated attacker submits a request to the nopriv AJAX handler rtb_stripe_pmt_succeed before the Stripe payment intent has been created for a booking (i.e., before the JavaScript-triggered create_stripe_pmtIntnt() call has stored an intent ID in post meta), the stripe_payment_intent_id property on the booking object remains null. The comparison sanitize_text_field(\u0027\u0027) == null evaluates to TRUE in PHP loose comparison, causing the payment verification check to pass with zero actual payment. This makes it possible for unauthenticated attackers to mark any existing payment_pending booking as paid without completing a Stripe payment by submitting an empty payment_id parameter."

    Title
    Five Star Restaurant Reservations – WordPress Booking Plugin <= 2.7.5 - Unauthenticated Stored Cross-Site Scripting
    Summary
    The Five Star Restaurant Reservations – WordPress Booking Plugin plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'rtb-name' parameter in all versions up to, and including, 2.7.5 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
