CVE-2021-32654
Nextcloud Server is a Nextcloud package that handles data storage.
Impact
Nextcloud Server is a Nextcloud package that handles data storage. In versions prior to 19.0.11, 20.0.10, and 21.0.2, an attacker is able to receive write/read privileges on any Federated File Share. Since public links can be added as federated file share, this can also be exploited on any public link. Users can upgrade to patched versions (19.0.11, 20.0.10 or 21.0.2) or, as a workaround, disable federated file sharing.

| Vendor | Product | Affected versions |
|---|---|---|
| Nextcloud | Nextcloud Server | before 19.0.11 from 20.0.0 before 20.0.10 from 21.0.0 before 21.0.2 |
