What the vulnerability does

01Description

The Booking Calendar Contact Form plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 1.2.60. This is due to missing authorization checks and payment verification in the `dex_bccf_check_IPN_verification` function. This makes it possible for unauthenticated attackers to arbitrarily confirm bookings and bypass payment requirements via the 'dex_bccf_ipn' parameter.

Explanation of Vulnerability in Simple Terms

The vulnerability requires no user interaction and can be exploited over the network. Site administrators should update to a version newer than 1.2.60 immediately.
