CVE-2026-9190

An HTTP request smuggling vulnerability in the HTTP App Server of Progress MarkLogic Server before 11.3.6 and 12.0.3 allows a remote attacker to bypass authentication and authorization checks, hijack a legitimate user's session, or capture credentials. The vulnerability occurs when a crafted HTTP request containing both Content-Length and Transfer-Encoding headers causes a reverse proxy and MarkLogic Server to interpret request boundaries differently.

Summary		(es) Una vulnerabilidad de contrabando de solicitudes HTTP en el Servidor de Aplicaciones HTTP de Progress MarkLogic Server anterior a 11.3.6 y 12.0.3 permite a un atacante remoto eludir los controles de autenticación y autorización, secuestrar la sesión de un usuario legítimo o capturar credenciales. La vulnerabilidad ocurre cuando una solicitud HTTP manipulada que contiene tanto los encabezados Content-Length como Transfer-Encoding hace que un proxy inverso y MarkLogic Server interpreten los límites de la solicitud de manera diferente.
