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.","state":0,"publishedAt":"2026-06-16T19:00:13+00:00","modifiedAt":"2026-07-20T14:00:25.677339+00:00","affected":[{"ecosystem":"npm","name":"n8n","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"2.26.0"},{"kind":"fixed","version":"2.26.2"}]}],"versions":[],"rawVersionEvidence":null},{"ecosystem":"npm","name":"n8n","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"2.25.7"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V3","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N","score":null,"severity":null},{"system":"CVSS_V4","vector":"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","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"MODERATE"}],"references":["https://github.com/n8n-io/n8n/security/advisories/GHSA-jvc7-762p-3743","https://nvd.nist.gov/vuln/detail/CVE-2026-54308","https://github.com/n8n-io/n8n"],"sourceUrl":"https://github.com/advisories/GHSA-jvc7-762p-3743","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-jvc7-762p-3743","identifiers":["GHSA-jvc7-762p-3743","CVE-2026-54308"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
