Nextcloud · Nextcloud Desktop Client · CVE-2021-22895
**Name of the Vulnerable Software and Affected Versions**
Nextcloud Desktop Client versions prior to 3.3.1
**Description**
The issue is related to the lack of SSL certificate verification when using the "Register with a Provider" flow in the Nextcloud Desktop Client, allowing a remote attacker to impact data integrity.
**Recommendations**
For versions prior to 3.3.1, update to version 3.3.1 or later to resolve the issue. As a temporary workaround, consider disabling the "Register with a Provider" flow until a patch is available. Restrict access to the affected flow to minimize the risk of exploitation.
