Vulnerability Title
undici vulnerable to downstream response splitting via retry interceptor
Vulnerability Description
undici's retry interceptor can append the body of a ranged retry response to bytes already delivered from an earlier partial response while still presenting the original response's status and headers. This happens when an upstream server delivers part of a body without a trustworthy resume checkpoint, for example a non-success response whose headers were already sent or a partial-content response with an unusable content range, then closes the connection and answers the resumed range request with more bytes. As a result the response body can be longer than the Content-Length that the application observes. An application that relays such a response to a downstream HTTP/1.1 peer without normalizing the framing can emit a body that exceeds the forwarded Content-Length, and the excess bytes can be interpreted as the start of a following response, which enables downstream response splitting or desynchronization. Exploitation requires an attacker-controlled upstream server and an application that forwards the response through a framing-sensitive path. This affects undici versions before 6.28.1, from 7.0.0 up to 7.29.1, and from 8.0.0 up to 8.10.2. Users should upgrade to undici 6.28.1, 7.29.1, or 8.10.2.

Vulnerability Title
undici 输入验证错误漏洞
Vulnerability Description
undici是undici组织的一个HTTP客户端库。 undici 6.28.1之前版本、7.0.0至7.29.1之前版本和8.0.0至8.10.2之前版本存在输入验证错误漏洞,该漏洞源于重试拦截器在无可信恢复检查点时将范围重试响应体附加至先前部分响应体后,且仍保留原始响应的状态和头信息,可能导致响应体超过Content-Length,造成下游响应拆分或响应去同步。
