{"id":"GHSA-jvc7-762p-3743","summary":"n8n: Missing Token Validation on Microsoft Agent 365 Trigger and Stripe Nodes","details":"## Impact\nThe `MicrosoftAgent365Trigger` and `StripeTrigger` node did not validate that inbound requests. As a result, an unauthenticated attacker who knows the webhook URL could submit a forged payload and cause the workflow to execute with attacker-controlled data.\n\n## Patches\nThe issue has been fixed in n8n versions 2.25.7, and 2.26.2. 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- Deactivate any workflows using the Microsoft Agent 365 Trigger node or Stripe Trigger node until the instance can be upgraded.\n- Restrict network access to the n8n webhook endpoint to trusted sources only.\n\nThese workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.","aliases":["CVE-2026-54308"],"modified":"2026-07-20T14:00:25.677339030Z","published":"2026-06-16T19:00:13Z","database_specific":{"nvd_published_at":"2026-06-23T17:17:07Z","cwe_ids":["CWE-290"],"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2026-06-16T19:00:13Z"},"references":[{"type":"WEB","url":"https://github.com/n8n-io/n8n/security/advisories/GHSA-jvc7-762p-3743"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-54308"},{"type":"PACKAGE","url":"https://github.com/n8n-io/n8n"}],"affected":[{"package":{"name":"n8n","ecosystem":"npm","purl":"pkg:npm/n8n"},"ranges":[{"type":"SEMVER","events":[{"introduced":"2.26.0"},{"fixed":"2.26.2"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/06/GHSA-jvc7-762p-3743/GHSA-jvc7-762p-3743.json"}},{"package":{"name":"n8n","ecosystem":"npm","purl":"pkg:npm/n8n"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2.25.7"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/06/GHSA-jvc7-762p-3743/GHSA-jvc7-762p-3743.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:L/VA:N/SC:L/SI:L/SA:N"}]}
