CVE-2026-64653

unknowncovered by 2 sourcesfirst seen 2026-08-06

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.

CSIRTS triage

What: Unescaped variable components in request URLs allow path traversal attacks.
Who is affected: Users of GitHub CLI versions containing this vulnerability when issuing API requests.
Urgency: Severity unknown; path traversal could lead to unauthorized resource access depending on context and endpoint.
Action: Update GitHub CLI to a patched version when released.
