{"id":"GHSA-gf29-4f56-r2jf","summary":"n8n: Git Node fetch/pull/pushTags Operations Bypass Sandbox Path Restriction","details":"## Impact\n\nAuthenticated n8n users with workflow create/execute rights could use the Git node's fetch, pull, or push-tags operations to bypass the repository-path containment checks that already protected clone and push. By pointing an allowlisted remote configuration value at a local path outside the intended sandbox, an attacker could pull an arbitrary local git repository into the workspace and subsequently read its files and history. \n\n## Patches\n\nThe issue has been fixed in n8n versions 1.123.67, 2.31.5, and 2.32.1. Users should upgrade to one of these versions or later to remediate the vulnerability.\n\n## Workarounds\n\nIf upgrading is not immediately possible, administrators should consider the following temporary mitigations:\n- Restrict n8n instance access to fully trusted users only.\n- Disable the Git node by adding `n8n-nodes-base.git` to the `NODES_EXCLUDE` environment variable.\n\nThese workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.","aliases":["CVE-2026-72770"],"modified":"2026-08-12T04:26:15.485822429Z","published":"2026-07-22T22:06:45Z","database_specific":{"cwe_ids":["CWE-22"],"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2026-07-22T22:06:45Z","nvd_published_at":null},"references":[{"type":"WEB","url":"https://github.com/n8n-io/n8n/security/advisories/GHSA-gf29-4f56-r2jf"},{"type":"WEB","url":"https://github.com/n8n-io/n8n/commit/f69dfc6dd2178a14ea1624d2e1d403c2e755042f"},{"type":"PACKAGE","url":"https://github.com/n8n-io/n8n"},{"type":"WEB","url":"https://github.com/n8n-io/n8n/releases/tag/n8n@1.123.67"},{"type":"WEB","url":"https://github.com/n8n-io/n8n/releases/tag/n8n@2.31.5"},{"type":"WEB","url":"https://github.com/n8n-io/n8n/releases/tag/n8n@2.32.1"}],"affected":[{"package":{"name":"n8n","ecosystem":"npm","purl":"pkg:npm/n8n"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"1.123.67"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/07/GHSA-gf29-4f56-r2jf/GHSA-gf29-4f56-r2jf.json"}},{"package":{"name":"n8n","ecosystem":"npm","purl":"pkg:npm/n8n"},"ranges":[{"type":"SEMVER","events":[{"introduced":"2.32.0"},{"fixed":"2.32.1"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/07/GHSA-gf29-4f56-r2jf/GHSA-gf29-4f56-r2jf.json"}},{"package":{"name":"n8n","ecosystem":"npm","purl":"pkg:npm/n8n"},"ranges":[{"type":"SEMVER","events":[{"introduced":"2.0.0-rc.0"},{"fixed":"2.31.5"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/07/GHSA-gf29-4f56-r2jf/GHSA-gf29-4f56-r2jf.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N"}]}
