CVE-2026-97401
In Kura versions <= 5.6.2, `CommandCloudApp.execute()` extracts a caller-supplied ZIP archive into a caller-supplied directory inside the Kura JVM process before dispatching the command to the executor service. On a packaged Kura installation the JVM runs as `kurad` with `CAP_DAC_OVERRIDE`, while the configurable "Unprivileged" executor drops to the `kura` user via `su`. A caller with permissions `rest.command` who is intentionally restricted to unprivileged command execution (`privileged.command.service.enable=false`, the default) can therefore set `workingDirectory` to `/` and use the ZIP body to write or overwrite arbitrary files on the device as `kurad`, completely bypassing the unprivileged sandbox the operator selected. The command service is disabled by default since Kura 4.0.0 [1]. The issue does not apply when the command service is disabled.
