CVE-2021-37631 Description

Deck is an open source kanban style organization tool aimed at personal planning and project organization for teams integrated with Nextcloud.

It is recommended that Nextcloud Deck is upgraded to 1.5.1, 1.4.4 or 1.2.9. If you are unable to update it is advised to disable the Deck plugin.
