Vulnerability Title
undici vulnerable to Denial of Service via orphaned RetryHandler response body
Vulnerability Description
undici's retry handler can leave an already-exposed response body pending forever. When a server returns a successful response that declares a Content-Length, sends only part of the body, and closes the connection, the retry handler retries the request. If the retry returns a non-retryable status such as 400, the handler forwards that new response downstream and replaces its internal response stream, but the original response body that the application still holds is never ended or destroyed. As a result calls that read that body never settle, and the configured body timeout does not fire because its timer is tied to the connection parser rather than the orphaned body. An attacker-controlled server can trigger this with two short responses without keeping a connection open, and repeated requests accumulate pending promises and streams that can exhaust application concurrency or memory. This affects undici versions from 7.11.0 up to 7.29.1 and from 8.0.0 up to 8.10.2. Users should upgrade to undici 7.29.1 or 8.10.2.

Vulnerability Title
undici 资源管理错误漏洞
Vulnerability Description
undici是undici组织的一个HTTP客户端库。 undici 7.11.0版本至7.29.1版本和8.0.0版本至8.10.2版本存在资源管理错误漏洞,该漏洞源于重试处理程序未正确处理已暴露的响应体,当服务器返回仅包含部分正文的成功响应并关闭连接时,原始响应体不会被结束或销毁,可能导致读取操作永久挂起,攻击者可通过两个短响应触发此问题,重复请求会累积未完成的promise和流,从而耗尽应用程序并发或内存。
