Kerentanan Uncontrolled Resource Consumption pada nextcloud calendar. Skor CVSS 3.1 4.3 (Medium) menurut NVD.

Deskripsi (NVD)

Nextcloud calendar is a calendar app for the Nextcloud server platform. Due to missing precondition checks the server was trying to validate strings of any length as email addresses even when megabytes of data were provided, eventually making the server busy and unresponsive. It is recommended that the Nextcloud Calendar app is upgraded to 4.4.4. The only workaround for users unable to upgrade is to disable the calendar app.
