MEDIUMPre-NVD 5.15.1—
EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 5.1 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.5%, top 59% 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 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.
