Nextcloud Files Access Control 1.14.1 Release Notes
This release fixes the following security issue: https://www.exploit-db.com/exploits/36759
Hashes of old versions of the Nextcloud Files Access Control app were published on exploit-db.com, which allowed an attacker to create fake profiles and use them to send out malicious links that could lead to arbitrary code execution in the Nextcloud instance.
The upgrade address this issue by requiring two factor authentication when creating a new Nextcloud account and by changing how URL hashes are calculated. Users who have already created a Nextcloud account with a vulnerable version will be notified when they log in to their account, so they can change their password before logging in again after updating their installation.
Note that this update will break compatibility with the Files Access Control iOS app for iPhones and iPads.
