Nextcloud Desktop client does not verify received singed certificate in end-to-end encryption
Summary
Nextcloud Desktop client does not verify received singed certificate in end-to-end encryption
Original description
The description as published by the source.
The Nextcloud Desktop Client is a tool to synchronize files from Nextcloud Server. Starting with version 3.0.0 and prior to version 3.7.0, by trusting that the server will return a certificate that belongs to the keypair of the user, a malicious server could get the desktop client to encrypt files with a key known to the attacker. This issue is fixed in Nextcloud Desktop 3.7.0. No known workarounds are available.
