CVE-2026-54728

bunkerweb is an Open-source and next-generation Web Application Firewall (WAF). Prior to BunkerWeb 1.6.12 and BunkerWeb PRO 0.57, authenticated Host header handling in the BunkerWeb UI and API improperly validated and neutralized user-controlled input in a configuration-dependent path, allowing a low-privileged authenticated user to escalate privileges and affect confidentiality, integrity, and availability of the BunkerWeb instance. This issue is fixed in BunkerWeb version 1.6.12 and BunkerWeb PRO version 0.57.

Summary		(es) bunkerweb es un cortafuegos de aplicaciones web (WAF) de código abierto y de próxima generación. Antes de BunkerWeb 1.6.12 y BunkerWeb PRO 0.57, el manejo autenticado del encabezado Host en la interfaz de usuario (UI) y la API de BunkerWeb validaba y neutralizaba incorrectamente la entrada controlada por el usuario en una ruta dependiente de la configuración, permitiendo a un usuario autenticado con pocos privilegios escalar privilegios y afectar la confidencialidad, integridad y disponibilidad de la instancia de BunkerWeb. Este problema está solucionado en la versión 1.6.12 de BunkerWeb y la versión 0.57 de BunkerWeb PRO.
