CVE-2026-41452

Krayin CRM 2.2.4 contains a missing authentication vulnerability in the installer middleware that allows unauthenticated remote attackers to overwrite the primary administrator account by sending a crafted HTTP POST request with the X-Requested-With: XMLHttpRequest header to bypass the CanInstall middleware redirect check. Attackers can supply arbitrary name, email, and password values to the admin-config-setup endpoint, which performs an unauthenticated updateOrInsert targeting the hardcoded administrator user ID, enabling full administrative access to all CRM data.

Summary		(es) Krayin CRM 2.2.4 contiene una vulnerabilidad de autenticación faltante en el middleware del instalador que permite a atacantes remotos no autenticados sobrescribir la cuenta de administrador principal enviando una solicitud HTTP POST manipulada con el encabezado X-Requested-With: XMLHttpRequest para eludir la verificación de redirección del middleware CanInstall. Los atacantes pueden proporcionar valores arbitrarios de nombre, correo electrónico y contraseña al endpoint admin-config-setup, que realiza una operación updateOrInsert no autenticada dirigida al ID de usuario de administrador codificado, lo que permite acceso administrativo completo a todos los datos del CRM.
