Vulnerability Title
blaze: Chunked-body trailer fields promoted into Request.headers in blaze-server (front-end header-sanitization bypass)
Vulnerability Description
blaze is a Scala library for building asynchronous pipelines, with a focus on network IO. Prior to 0.23.18 and 1.0.0-M42, blaze-server can merge HTTP/1.1 chunked-body trailer fields into Request.headers. Because trailer fields are attacker-controlled, an unauthenticated remote client can inject arbitrary header names and values, including X-Forwarded-For and internal authorization headers, that a fronting proxy sanitized from the request-header section, bypassing header-based trust decisions in the application. Any http4s application using BlazeServerBuilder over HTTP/1.1 whose routes or middleware trust proxy-set headers, including X-Forwarded-For, X-Real-IP, and X-Forwarded-Host, is affected. If a fronting proxy strips or normalizes those headers but forwards chunked bodies with trailers intact, an attacker can spoof client IP for allow-lists, rate limits, or auditing, forge the https scheme, or inject internal authorization headers. A promoted Connection: close trailer is also honored, allowing attacker-controlled termination of pooled backend connections. This issue is fixed in versions 0.23.18 and 1.0.0-M42.

Vulnerability Title
http4s blaze 输入验证错误漏洞
Vulnerability Description
http4s blaze是http4s组织的一款Web中间件组件。 http4s blaze 0.23.18之前版本和1.0.0-M42之前版本存在输入验证错误漏洞,该漏洞源于blaze-server将HTTP/1.1分块传输的trailer字段合并到Request.headers中,未经身份验证的远程攻击者可注入任意标头和值,绕过基于标头的信任决策,可能导致伪造客户端IP、伪造https协议、注入内部授权头或终止后端连接。
