      "value": "Grav before 2.0.4 ships a default .htaccess (and reference webserver-configs/htaccess.txt) whose rules blocking access to sensitive file types (.yaml, .php, .json, etc.) lack the [NC] flag, making extension matching case-sensitive. On case-insensitive filesystems (Windows/NTFS, macOS/HFS+, or Docker volume mounts), an unauthenticated attacker can request these files with uppercase or mixed-case extensions (e.g., .YAML, .PHP) to bypass the restrictions and read sensitive configuration files that may contain API keys and credentials."

      "value": "Grav anterior a la versión 2.0.4 incluye un archivo .htaccess predeterminado (y el archivo de referencia webserver-configs/htaccess.txt) cuyas reglas que bloquean el acceso a tipos de archivos sensibles (.yaml, .php, .json, etc.) carecen de la bandera [NC], lo que hace que la coincidencia de la extensión distinga entre mayúsculas y minúsculas. En sistemas de archivos que no distinguen entre mayúsculas y minúsculas (Windows/NTFS, macOS/HFS+, o montajes de volumen de Docker), un atacante no autenticado puede solicitar estos archivos con extensiones en mayúsculas o con una combinación de mayúsculas y minúsculas (por ejemplo, .YAML, .PHP) para eludir las restricciones y leer archivos de configuración sensibles que pueden contener claves de API y credenciales."
