A CSRF issue was discovered in DAViCal through 1.1.8. If an authenticated user visits an attacker-controlled webpage, the attacker can send arbitrary requests in the name of the user to the application. If the attacked user is an administrator, the attacker could for example add a new admin user.
The web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor.
