  "summary": "CVE-2026-59831 is fixed in 2 products on 2 platforms, first by GitHub CLI 2.96.0, released July 2, 2026. It is not reported as exploited. Patch Radar priority: Routine.",
  "title": "GitHub CLI \u0060gh codespace jupyter\u0060 could allow remote code execution when connecting to a malicious Codespace",
  "description": "GitHub CLI (gh) is GitHub\u2019s official command line tool. From 2.10.0 through 2.95.0, connecting to a malicious Codespace with gh codespace jupyter can allow command execution because the command opens a JupyterLab URL supplied by a process inside the Codespace without validating that it is a loopback HTTP or HTTPS address, allowing a crafted vscode:// or vscode-insiders:// URL to be handed to VS Code. This issue is fixed in version 2.96.0.",
