CVE-2026-9190

Full vulnerability record from the local CVENow database.

Description

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.

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."
