What is CVE-2026-45152?
CVE-2026-45152 is a high-severity command injection vulnerability in uniget-org cli, published on 27 May 2026. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Official 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.
Weakness: CWE-78
