Server

Gotify server is a simple server for sending and receiving messages in real-time per WebSocket. Prior to 3.0.0, the password change endpoint (POST /current/user/password) accepts a valid client token without requiring the account's current password or another elevated authentication step. An attacker who obtains a client token can set a new password for the associated user, taking control of password authentication and forcing account recovery through an administrator or direct database access. This issue is fixed in version 3.0.0.

Gotify server is a simple server for sending and receiving messages in real-time per WebSocket. Versions prior to 2.2.2 contain an XSS vulnerability that allows authenticated users to upload .html files. An attacker could execute client side scripts **if** another user opened a link. The attacker could potentially take over the account of the user that clicked the link. The Gotify UI won't natively expose such a malicious link, so an attacker has to get the user to open the malicious link in a context outside of Gotify. The vulnerability has been fixed in version 2.2.2. As a workaround, you can block access to non image files via a reverse proxy in the `./image` directory.
