CVE-2026-64654

Summary

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.
