A value containing URL path metacharacters can alter the request path and cause `gh` to address a different resource than intended.\n\n### Details\n\nNot all request URLs in the codebase were built with proper escaping of their variable path components. When a component is interpolated into the path without percent encoding, and that component contains URL path metacharacters, it breaks out of its intended segment and changes the effective request path.\n\nIn `2.97.0`, request URLs are constructed in a safe manner, so a variable component can no longer escape its intended segment.\n\n### Impact\n\nAn attacker who can control a value that flows into a request path can cause `gh` to send the request to a different API endpoint than intended. This can lead the CLI to read or act on a resource other than the one the user meant to target.\n\n### Remediation and Mitigation\n\n1. Upgrade `gh` to `2.97.0`.\n2. Be cautious when running `gh` against untrusted repositories or inputs whose names you do not control.","state":0,"publishedAt":"2026-10-15T18:07:14+00:00","modifiedAt":"2026-10-19T21:40:57.7024508+00:00","affected":[{"ecosystem":"Go","name":"github.com/cli/cli/v2","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"2.97.0"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V4","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:N/VI:N/VA:N/SC:L/SI:N/SA:N","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"LOW"}],"references":["https://github.com/cli/cli/security/advisories/GHSA-4fjg-2h4q-fwg3","https://nvd.nist.gov/vuln/detail/CVE-2026-64653","https://github.com/cli/cli/commit/0c2eea6338a2323cfff000160b9b5a56a38d2a06","https://github.com/cli/cli","https://github.com/cli/cli/releases/tag/v2.97.0"],"sourceUrl":"https://github.com/advisories/GHSA-4fjg-2h4q-fwg3","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-4fjg-2h4q-fwg3","identifiers":["GHSA-4fjg-2h4q-fwg3","CVE-2026-64653","GO-2026-6765"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
