Description

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.
