CVE-2026-60021— Gitea GitLab migration denial of service

Quick assessment

Affected
Gitea Gitea
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.

Gitea 的初始 GitLab 迁移版本探测功能使用的是没有设置超时的 HTTP 客户端，并且未关联迁移任务的取消上下文（cancellation context）。具备启动迁移权限的已认证用户可将目标指向由攻击者控制的服务器，该服务器会无限期保持响应开放。即使任务已被取消，该请求仍会继续执行，从而导致迁移工作池被耗尽，阻止其他迁移任务的正常进行。

Vulnerability Title
Gitea GitLab migration denial of service
Source: CVE Program / CVE List V5
Vulnerability Description
Gitea's initial GitLab migration version probe uses an HTTP client without a timeout and does not attach the migration task's cancellation context. An authenticated user who can start migrations can target an attacker-controlled server that keeps the response open indefinitely. The request continues after task cancellation and can exhaust the migration worker pool, preventing other migrations from progressing.
