Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The go-gh Go module (github.com/cli/go-gh/v2) before 2.12.1 is vulnerable. An attacker-controlled GitHub Enterprise Server could replace URLs in API responses with local executable paths, and when a user runs a gh command that opens a browser, this could execute arbitrary executables on the user's machine. Upgrade go-gh to 2.12.1 or later.
