      "value": "An issue was discovered in Cinnamon kotaemon 0.11.0. The _may_extract_zip function in the \\libs\\ktem\\ktem\\index\\file\\ui.py file does not check the contents of uploaded ZIP files. Although the contents are extracted into a temporary folder that is cleared before each extraction, successfully uploading a ZIP bomb could still cause the server to consume excessive resources during decompression. Moreover, if no further files are uploaded afterward, the extracted data could occupy disk space and potentially render the system unavailable. Anyone with permission to upload files can carry out this attack."

      "value": "Se descubrió un problema en Cinnamon kotaemon 0.11.0. La función _may_extract_zip en el archivo \\libs\\ktem\\ktem\\index\\file\\ui.py no verifica el contenido de los archivos ZIP subidos. Aunque el contenido se extrae en una carpeta temporal que se limpia antes de cada extracción, la carga exitosa de una bomba ZIP aún podría provocar que el servidor consuma recursos excesivos durante la descompresión. Además, si no se suben más archivos posteriormente, los datos extraídos podrían ocupar espacio en disco y potencialmente dejar el sistema no disponible. Cualquiera con permiso para subir archivos puede llevar a cabo este ataque."
