Summary
go-gh before version 2.12.1 allowed an attacker-controlled GitHub Enterprise Server to execute arbitrary commands on a user's machine by replacing HTTP URLs with local file paths for browsing.
Risk Assessment
A user can be tricked into opening a malicious link, potentially leading to arbitrary code execution on their machine, posing a serious security threat.
Recommendation
Update go-gh to version 2.12.1, which includes fixes in Browser.Browse() to prevent opening or executing local files.
Original NVD description (English source)
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.
