Quick assessment

Affected
go-vikunja vikunja
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.

Vikunja 在 2.2.0 至 2.7.0（不含）版本中存在过于宽松的跨域资源共享（CORS）配置问题：该配置会信任所有 localhost 和 127.0.0.1 端口的请求并携带凭证（credentials），即使已设置 参数。攻击者若能控制任意 localhost 端口上的页面，即可向令牌刷新端点发送带凭证的请求，读取返回的 Bearer JWT 令牌，从而劫持已登录用户的账户。
