CVE-2026-73117— Apache Juneau: Response header CRLF injection and open redirect when applications set headers or redirect targets from request data

Quick assessment

Affected
Apache Software Foundation Apache Juneau
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.

Apache Juneau 中存在 HTTP 响应头中 CRLF 序列未正确中和的漏洞（即"HTTP 响应拆分”漏洞）。 Apache Juneau REST 服务器将响应头值和重定向目标未经检查地传递给了 Servlet 容器。如果应用程序从请求数据中设置响应头或重定向目标，则可能允许远程客户端注入新的 HTTP 头行（前提是 Servlet 容器本身未拒绝 CR/LF 字符），或将用户重定向到任意外部站点。该框架本身不会从请求数据构建响应头或重定向；是否暴露此风险取决于应用程序代码。 此问题影响 Apache

Vulnerability Title
Apache Juneau: Response header CRLF injection and open redirect when applications set headers or redirect targets from request data
Source: CVE Program / CVE List V5
Vulnerability Description
Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Response Splitting') vulnerability in Apache Juneau. The Apache Juneau REST server passed response header values and redirect targets to the servlet container unchecked. An application that sets a response header or redirect target from request data could let a remote client inject header lines (where the servlet container does not itself reject CR/LF) or redirect users to an arbitrary external site. The framework itself does not build headers or redirects from request data; exposure depends on application code. This issue affects Apache Juneau: through 9.2.0. Users are recommended to upgrade to version 9.2.1, which fixes the issue. Header values are now sanitized by default; applications that build redirect targets from request data must also switch from sendRedirect() to the new sendSafeRedirect().
