CVE-2022-3852Network attack vector

Calendar and settings modification via missing nonce validation

Published Nov 3, 2022 · Updated Apr 8, 2026

Cross-site request forgery in Innate Images LLC VR Calendar 2.3.3 and earlier allows remote attackers to alter calendars and settings. Administrative handlers in VRCalendarAdmin.class.php process state-changing calendar and settings requests without verifying a WordPress nonce. Exploitation requires a logged-in site administrator to open an attacker-controlled link, enabling calendar deletion or modification and plugin-settings changes under that session.
