CVE-2026-45152 Details
Description
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.
A command injection vulnerability allowing arbitrary code execution has been identified in uniget, a universal installer and updater for container tools. This vulnerability exists in versions through 0.27.0, with the issue arising from the unsafe execution of the 'check' field in metadata files using '/bin/bash -c'. The 'check' field is loaded directly from untrusted JSON metadata without any validation or sanitization, enabling attackers to craft malicious metadata that executes arbitrary shell commands on the victim's system. This exploitation occurs during common uniget operations such as describe, install, update, or inspect. The vulnerability can be exploited to execute arbitrary code with the privileges of the user running uniget.
Users are advised to update to uniget version 0.27.1 or later, where this vulnerability has been fixed.
