Medium (5.1). EPSS 0.5% chance of exploitation in the next 30 days. Fixed in github.com/cli/cli/v2 2.97.0.
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.
