{"id":"GHSA-64xh-79j6-r5v8","summary":"n8n: Bypass \"Allowed HTTP Request Domains\" Credential Restriction in Multiple AI and LLM Nodes","details":"## Impact\n\nThe credential \"Allowed HTTP Request Domains\" allowlist was intended to restrict which hosts a credential's secret could be sent to, protecting shared credentials from users who could use but not view them. Several AI/LLM nodes did not enforce this allowlist when a user-supplied base or endpoint URL was set. A low-privileged workflow editor with use-only access to such a shared credential could point one of these nodes at an attacker-controlled host and cause the credential secret to be transmitted there, then reuse it against the underlying service.\n\nOnly instances where a credential has \"Allowed HTTP Request Domains\" configured and is shared with non-owner users are affected.\n\n## Patches\nThe issue has been fixed in n8n versions 2.31.5 and 2.32.1. Users should upgrade to one of these versions or later to remediate the vulnerability.\n\n## Workarounds\nIf upgrading is not immediately possible, administrators should consider the following temporary mitigations:\n- Restrict workflow creation and editing permissions to fully trusted users only.\n- Restrict credential sharing to fully trusted users only.\n- Audit credentials with domain restrictions for unexpected sharing relationships.\n\nThese workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.","aliases":["CVE-2026-72771"],"modified":"2026-08-12T04:26:18.532795233Z","published":"2026-07-22T22:06:06Z","database_specific":{"nvd_published_at":null,"cwe_ids":["CWE-863"],"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2026-07-22T22:06:06Z"},"references":[{"type":"WEB","url":"https://github.com/n8n-io/n8n/security/advisories/GHSA-64xh-79j6-r5v8"},{"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@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":"2.32.0"},{"fixed":"2.32.1"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/07/GHSA-64xh-79j6-r5v8/GHSA-64xh-79j6-r5v8.json"}},{"package":{"name":"n8n","ecosystem":"npm","purl":"pkg:npm/n8n"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2.31.5"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/07/GHSA-64xh-79j6-r5v8/GHSA-64xh-79j6-r5v8.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:L/SI:N/SA:N"}]}
