CVE-2026-45152: CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in uniget-org cli
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.
AI Analysis
Technical Summary
The uniget CLI tool versions before 0.27.1 contain an OS command injection vulnerability (CWE-78) due to unsafe execution of the 'check' field from metadata files. The 'check' field is loaded directly from untrusted JSON metadata and executed using '/bin/bash -c' without any validation or sanitization. This flaw allows attackers to execute arbitrary shell commands on the victim's system with the privileges of the user running uniget when performing common operations such as describe, install, update, or inspect. The vulnerability is addressed in version 0.27.1 of uniget.
Potential Impact
Successful exploitation of this vulnerability can lead to arbitrary code execution with the privileges of the user running the uniget CLI. This can result in complete compromise of the affected system under that user's context, including confidentiality, integrity, and availability impacts. There are no known exploits in the wild at this time.
Mitigation Recommendations
This vulnerability is fixed in uniget version 0.27.1. Users should upgrade to version 0.27.1 or later to remediate this issue. Since no official patch link or advisory is provided, users should verify the upgrade from the official uniget project sources. Patch status is not yet confirmed by a vendor advisory; check the uniget project for the latest remediation guidance.
