Is 网盘万能助手 safe?

Low risk

网盘万能助手 copies your Baidu BDUSS session cookie into Baidu page localStorage.

On Baidu Netdisk pages, the extension asks its background script for the BDUSS cookie from baidu.com and writes it into page localStorage. That makes the session cookie available to JavaScript running in the Baidu page origin as baiduyunPlugin_BDUSS.
