Overview

What is CVE-2026-64654?

GitHub CLI (gh) is GitHub's official command line tool. Prior to version 2.97.0, multiple GitHub CLI commands printed externally controlled gist, API, pull request, release, codespace, skill, or agent-task content without neutralizing terminal escape sequences.

An attacker who can influence that content can embed escape sequences that are interpreted by the terminal of a user who runs an affected command, with impact ranging from cosmetic manipulation of the title or on-screen content to, on some terminal emulators, command execution. This extends the same class of issue as CVE-2026-45803—which addressed only gh run view --log—to the other affected command paths.

This issue is fixed in version 2.97.0.
