CVE-2026-9190
CriticalCVSS 9.1Summary
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.
Risk Assessment
Risk of bypassing security controls, session hijacking, and credential theft, potentially leading to unauthorized access to the system and data.
Recommendation
Upgrade Progress MarkLogic Server to version 11.3.6 or 12.0.3 (or later). Additionally, configure the reverse proxy consistently with MarkLogic Server regarding header handling.
