# CVE-2026-114359: CVE-2026-114359

Status: published. Published: 2026-11-10. Updated: 2026-11-10.

Eclipse Kura downloads deployment packages (DPs) from a remote URL without any limit on the size of the data it receives. A malicious or compromised HTTP(S) server, or an attacker able to tamper with a plain-HTTP download, can stream an arbitrarily large (or endless) response. Kura writes the response to local storage until the filesystem is full. On gateways the temporary directory is often a RAM-backed tmpfs, so this can also exhaust memory. The result is denial of service of the device: failed configuration persistence, failed logging and possible crashes of the framework or other services.



The same missing size limit is present in the REST upload endpoint `POST /deploy/v2/_upload`, which copies the request body to the temporary directory with no limit.



Workarounds: only install DPs from trusted HTTPS sources, restrict who can install packages (Web UI `kura.packages.admin` permission, REST `kura.permission.rest.deploy`, cloud DEPLOY-V2 access).
