Vulnerability Overview
The Online Booking & Scheduling Calendar for WordPress by vcita plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 4.5. This is due to missing or incorrect nonce validation on the vcita_save_settings_callback() function. This makes it possible for unauthenticated attackers to save settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site.
CWE-352: Cross-Site Request Forgery (CSRF)
Online Booking & Scheduling Calendar for WordPress by vcita <= 4.5 carries this weakness at vcita_save_settings_callback(), and reaching it takes a caller who can reach the endpoint. Cross-site request forgery abuses the fact that browsers attach a victim's cookies to any request, so a state-changing action that only checks who you are, not whether you meant to act, can be triggered from another site.
An attacker who gets a logged-in user to load a crafted page can perform that action as them, with the impact scaling to whatever the victim's role is allowed to do. For Online Booking & Scheduling Calendar for WordPress by vcita the fix is 4.5.2: builds <= 4.5 are affected, anything from 4.5.2 onward is not.
Remediation
Update to version 4.5.2, or a newer patched version
