CVE-2021-32734: Nextcloud Server

Medium severity, CVSS 5.3. EPSS: 1.4% chance of exploitation in the next 30 days.

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.

Affected products

• Nextcloud Nextcloud Server: before 19.0.13 (fixed in 19.0.13); from 20.0.0, before 20.0.11 (fixed in 20.0.11); from 21.0.0, before 21.0.3 (fixed in 21.0.3)
