CVE-2021-32734 Information

Description

Nextcloud Server is a Nextcloud package that handles data storage. In versions prior to 19.0.13 20.011 and 21.0.3 the Nextcloud Text application shipped with Nextcloud Server returned verbatim exception messages to the user. This could result in a full path disclosure on shared files. The issue was fixed in versions 19.0.13 20.0.11 and 21.0.3. As a workaround one may disable the Nextcloud Text application in Nextcloud Server app settings.
