CVE-2025-10148— curl 安全漏洞

predictable WebSocket mask

curl's websocket code did not update the 32 bit mask pattern for each new outgoing frame as the specification says. Instead it used a fixed mask that persisted and was used throughout the entire connection. A predictable mask pattern allows for a malicious server to induce traffic between the two communicating parties that could be interpreted by an involved proxy (configured or transparent) as genuine, real, HTTP traffic with content and thereby poison its cache. That cached poisoned content could then be served to all users of that proxy.

curl 安全漏洞

curl是cURL开源的一款用于从服务器传输数据或向服务器传输数据的工具。 curl存在安全漏洞，该漏洞源于websocket代码未按照规范为每个新出站帧更新32位掩码模式，而是使用固定掩码，可能导致恶意服务器诱导流量被代理服务器误认为真实HTTP流量，从而污染其缓存。
