{"id":"GHSA-fxcw-h3qj-8m8p","summary":"n8n Has External Secrets Authorization Bypass in Credential Saving","details":"## Impact\nAn authenticated user without permission to list external secrets could reference a secret by the external name in a credential and retrieve its plaintext value when saving the credential. This bypassed the `externalSecret:list` permission check and allowed access to secrets stored in connected vaults without admin or owner privileges.\n\n- This issue requires the instance to have an external secrets vault configured.\n- The attacker must know or be able to guess the name of a target secret.\n\n## Patches\nThe issue has been fixed in n8n versions 1.123.23 and 2.6.4. 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 n8n access to fully trusted users only.\n- Disable external secrets integration until the patch can be applied.\n\nThese workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.","aliases":["CVE-2026-33722"],"modified":"2026-03-25T22:26:20.888233Z","published":"2026-03-25T22:05:44Z","database_specific":{"cwe_ids":["CWE-863"],"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2026-03-25T22:05:44Z","nvd_published_at":"2026-03-25T19:16:51Z"},"references":[{"type":"WEB","url":"https://github.com/n8n-io/n8n/security/advisories/GHSA-fxcw-h3qj-8m8p"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-33722"},{"type":"PACKAGE","url":"https://github.com/n8n-io/n8n"}],"affected":[{"package":{"name":"n8n","ecosystem":"npm","purl":"pkg:npm/n8n"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"1.123.23"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/03/GHSA-fxcw-h3qj-8m8p/GHSA-fxcw-h3qj-8m8p.json"}},{"package":{"name":"n8n","ecosystem":"npm","purl":"pkg:npm/n8n"},"ranges":[{"type":"SEMVER","events":[{"introduced":"2.0.0-rc.0"},{"fixed":"2.6.4"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/03/GHSA-fxcw-h3qj-8m8p/GHSA-fxcw-h3qj-8m8p.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:N/A:N"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:N/VA:N/SC:H/SI:H/SA:H"}]}
