Medium (6.5) in nextcloud end-to-end encryption. EPSS 0.5% chance of exploitation in the next 30 days.
Nextcloud End-to-end encryption app provides all the necessary APIs to implement End-to-End encryption on the client side. By providing an invalid meta data file, an attacker can make previously dropped files inaccessible. It is recommended that the Nextcloud End-to-end encryption app is upgraded to version 1.12.4 that contains the fix.
