CVE-2026-8795

A YAML injection vulnerability exists in the Windows.Collectors.Remapping artifact of Rapid7 Velociraptor before version 0.76.6. The hostname field in client_info.json inside a collection ZIP is inserted into a YAML template via Go's text/template without escaping. An attacker providing a crafted collection ZIP can leverage literal double quotes and newlines in the hostname to break out of the YAML quoted string and inject a new mount remapping entry. When an analyst applies the generated remapping file with --remap, arbitrary VQL executes on their machine with NullACLManager (all permissions granted, unsandboxed).

Summary		(es) Una vulnerabilidad de inyección YAML existe en el artefacto Windows.Collectors.Remapping de Rapid7 Velociraptor anterior a la versión 0.76.6. El campo hostname en client_info.json dentro de un ZIP de colección se inserta en una plantilla YAML a través de text/template de Go sin escapar. Un atacante que proporciona un ZIP de colección manipulado puede aprovechar comillas dobles literales y saltos de línea en el hostname para salir de la cadena citada de YAML e inyectar una nueva entrada de reasignación de montaje. Cuando un analista aplica el archivo de reasignación generado con --remap, VQL arbitrario se ejecuta en su máquina con NullACLManager (todos los permisos concedidos, sin sandbox).
