CVE-2023-2416

Name of the Vulnerable Software and Affected Versions The Online Booking & Scheduling Calendar for WordPress by vcita plugin for WordPress versions up to, and including, 4.2.10

Description The issue is related to a missing nonce check on the vcita logout callback function, which makes it possible for unauthenticated attackers to logout a vcita connected account. This can cause a denial of service on the appointment scheduler via a forged request, granted they can trick a site user into performing an action such as clicking on a link.

Recommendations For versions up to, and including, 4.2.10, update to a version that includes a fix for the missing nonce check on the vcita logout callback function to prevent Cross-Site Request Forgery attacks. As a temporary workaround, consider restricting access to the vcita logout callback function until a patch is available.
