CVE-2026-55061 Details
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.
A command injection vulnerability has been identified in uniget, a universal installer and updater for container tools, prior to version 0.27.6. The issue arises in the hooks edit command, where the application improperly parses the UNIGET_EDITOR or EDITOR environment variables. This flawed parsing allows an attacker to inject unexpected arguments that could be executed with the privileges of the uniget process. Although the vulnerability does not involve shell command interpretation, it could still be exploited to perform unintended actions.
Users can update to uniget version 0.27.6 or later, where this vulnerability has been fixed.
