EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 5.3 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.7%, top 47% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.
