CVE-2025-5936Network attack vector

Unauthorized calendar synchronization via missing nonce validation

Published Jun 27, 2025 · Updated Apr 8, 2026

Cross-site request forgery in Innate Images LLC VR Calendar 2.4.7 and earlier allows remote attackers to trigger calendar synchronization. The syncCalendar() administrative action accepts a state-changing request without correctly validating a WordPress nonce, so a forged request executes through an administrator's session. Exploitation requires a logged-in site administrator to follow an attacker-controlled link, and the resulting action changes calendar synchronization state.
