CVE-2026-64653

Name	CVE-2026-64653
Description	GitHub CLI (gh) is GitHub’s official command line tool. Prior to 2.97.0, some HTTP request URLs interpolate variable path components without percent encoding, allowing URL path metacharacters in attacker-controlled repository or resource values to make gh address a different API endpoint or resource than the user intended. This issue is fixed in version 2.97.0.
