Description Marian Rehak 2022-03-14 15:16:59 UTC 
Due to an issue with the Nextcloud Text application, which is by default shipped with Nextcloud Server, an attacker is able to access the folder names of "File Drop". For successful exploitation an attacker requires knowledge of the sharing link. Users unable to upgrade should disable the Nextcloud Text application in the application settings.
