CVE-2026-102603— Gotify: Insufficiently Protected Password Change endpoint

Quick assessment

Affected
gotify server
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Gotify 服务器是一个基于 WebSocket 的简单实时消息收发服务器。在 3.0.0 版本之前，密码修改端点（POST /current/user/password）在未要求提供账户当前密码或其他更高权限认证步骤的情况下，仅凭有效的客户端令牌（client token）即可接受请求。攻击者一旦获取该客户端令牌，便可重置关联用户的新密码，从而接管密码认证权限，并迫使账户需要通过管理员或直接数据库访问来进行恢复。此问题已在 3.0.0 版本中得到修复。

Vulnerability Title
Gotify: Insufficiently Protected Password Change endpoint
Source: CVE Program / CVE List V5
Vulnerability Description
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.
