Summary
Details

go-gh is a collection of Go modules to make authoring GitHub CLI extensions easier. A security vulnerability has been identified in versions prior to 2.12.1 where an attacker-controlled GitHub Enterprise Server could result in executing arbitrary commands on a user's machine by replacing HTTP URLs provided by GitHub with local file paths for browsing. In 2.12.1, Browser.Browse() has been enhanced to allow and disallow a variety of scenarios to avoid opening or executing files on the filesystem without unduly impacting HTTP URLs. No known workarounds are available other than upgrading.
