Description

The Calendar Event Multi View WordPress plugin before 1.4.07 does not have any authorisation and CSRF checks in place when creating an event, and is also lacking sanitisation as well as escaping in some of the event fields. This could allow unauthenticated attackers to create arbitrary events and put Cross-Site Scripting payloads in it.

Affected products

Calendar Event Multi View: before 1.4.07 — fixed in 1.4.07

How to fix

Upgrade to a fixed version: Calendar Event Multi View 1.4.07. Check the vendor advisory for mitigations.
