CVE-2026-45152

uniget is a universal installer and updater for (container) tools. Prior to 0.27.1, a command injection vulnerability exists in uniget due to unsafe execution of the check field from metadata files using /bin/bash -c. Because the check field is loaded directly from untrusted JSON metadata without validation or sanitization, an attacker can craft malicious metadata that executes arbitrary shell commands on the victim’s system when common uniget operations such as describe, install, update, or inspect are performed. This vulnerability can lead to arbitrary code execution with the privileges of the user running uniget. This vulnerability is fixed in 0.27.1.

Summary		(es) uniget es un instalador y actualizador universal para herramientas (de contenedor). Antes de 0.27.1, existe una vulnerabilidad de inyección de comandos en uniget debido a la ejecución insegura del campo check de los archivos de metadatos usando /bin/bash -c. Debido a que el campo check se carga directamente de metadatos JSON no confiables sin validación ni saneamiento, un atacante puede crear metadatos maliciosos que ejecutan comandos de shell arbitrarios en el sistema de la víctima cuando se realizan operaciones comunes de uniget como describe, install, update o inspect. Esta vulnerabilidad puede conducir a la ejecución de código arbitrario con los privilegios del usuario que ejecuta uniget. Esta vulnerabilidad se corrige en 0.27.1.
