{"id":"DEBIAN-CVE-2026-59831","details":"GitHub CLI (gh) is GitHub’s 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.","modified":"2026-09-14T17:03:46.910679827Z","published":"2026-07-09T23:17:05.483Z","upstream":["CVE-2026-59831"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-59831"}],"affected":[{"package":{"name":"gh","ecosystem":"Debian:12","purl":"pkg:deb/debian/gh?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.23.0+dfsg1-1","2.24.3+dfsg1-1","2.27.0+dfsg1-1","2.30.0-1","2.30.0-2","2.35.0-1","2.40.1+dfsg1-1","2.42.1-1","2.43.1-1","2.44.1-1","2.44.1-2","2.45.0-1","2.46.0-1","2.46.0-2","2.46.0-3","2.46.0-4"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-59831.json"}},{"package":{"name":"gh","ecosystem":"Debian:13","purl":"pkg:deb/debian/gh?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.46.0-3","2.46.0-4"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-59831.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:C/C:L/I:L/A:N"}]}
