Summary

In uniget before version 0.27.6, the hooks edit command in cmd/uniget/hooks.go parses UNIGET_EDITOR or EDITOR with strings.Split(editor, " ") and passes every space-delimited suffix as an argument to the selected editor executable. An attacker who can influence the editor environment and cause hook editing can supply unexpected editor arguments, potentially causing unintended actions with the privileges of the uniget process account. Go os/exec does not evaluate shell operators in these arguments.

Risk Assessment

An attacker able to control the editor environment variable can force unintended actions with the privileges of the uniget process, potentially leading to file modification or other side effects. Shell command interpretation has not been demonstrated.

Recommendation

Upgrade uniget to version 0.27.6 or later. Restrict the ability of untrusted parties to modify the UNIGET_EDITOR and EDITOR environment variables.

Other vulnerabilities in uniget

CVE-2026-55062High
In uniget (a universal installer and updater for container tools) before version 0.27.6, the hooks edit command in cmd/uniget/hooks.go concatenates an unvalidated hook filename with the selected hooks directory, allowing parent-directory components to escape that directory. The resulting path is passed to the configured editor, which can access or modify files outside the hooks directory with the privileges of the uniget process account. The issue is fixed in version 0.27.6.

Original NVD description (English source)

uniget is a universal installer and updater for (container) tools. Prior to 0.27.6, the hooks edit command in cmd/uniget/hooks.go parses UNIGET_EDITOR or EDITOR with strings.Split(editor, " ") and passes every space-delimited suffix as an argument to the selected editor executable. An attacker who can influence the editor environment and cause hook editing can supply unexpected editor arguments, potentially causing unintended actions with the privileges of the uniget process account. Go os/exec does not evaluate shell operators in these arguments, so the advisory's wrapper demonstration establishes argument delivery but does not establish shell command interpretation. This issue is fixed in version 0.27.6.
