  "title": "HTTP response splitting in Apache Juneau",
  "summary": "Apache Juneau REST server through 9.2.0 can pass application-provided response header values and redirect targets without framework-level validation. A remote attacker may inject response headers or cause an external redirect when an application derives these values from request input; header injection also depends on the servlet container accepting CR/LF.",
