n8n >= 0.123.0 and < 1.121.3 - Remote Code Execution

n8n versions = 0.123.0 and = 0.123.0 and = 0.123.0 and 1.121.3 contain a critical authenticated remote code execution vulnerability via arbitrary file write. An authenticated user can exploit the Git node to overwrite critical files and execute untrusted code on the n8n server, potentially leadin...

n8n Webhooks - Remote Code Execution

n8n is an open source workflow automation platform. Versions starting with 1.65.0 and below 1.121.0 enable an attacker to access files on the underlying server through execution of certain form-based workflows. A vulnerable workflow could grant access to an unauthenticated remote attacker,...

n8n - Remote Code Execution via Expression Injection

n8n 1.120.4, 1.121.1, 1.122.0 contains a remote code execution caused by insufficient isolation in workflow expression evaluation, letting authenticated attackers execute arbitrary code with n8n process privileges. Exploit requires authentication. id: CVE-2025-68613 info: name: n8n - Remote Code...

GHSA-Q5XF-XHWF-CWQF n8n: Member-Level Users Can Execute Other Users' MCP Server Trigger Workflows via Missing OAuth Authorization Check

Impact The OAuth 2.1 consent and token-issuance flow introduced in n8n 2.27.0 does not verify that the authenticated user has access to the workflow referenced as the OAuth resource. A member-level user can register an OAuth client, self-approve consent for another user's n8n OAuth2-protected MCP...

GHSA-2XGM-WC4G-5JVG n8n: Improper Authorization Allows Authenticated Users to Assign Workflows to Folders in Other Projects

Impact An authenticated user with permission to create workflows in one project could bypass project/folder authorization boundaries during workflow creation. By supplying a crafted request payload, the user could associate a newly created workflow with a folder belonging to a different project...

GHSA-2X35-3FW4-9JR4 n8n: Send Email Node Arbitrary File Read and SSRF via Nodemailer Content-Object Type Confusion

Impact The n8n Send Email node did not enforce that its message fields were strings, so a crafted untrusted non-string value from a workflow expression could be treated by the underlying mail library as a file path or URL. This could allow disclosure of local files on the n8n host. Exploitation...

GHSA-GF29-4F56-R2JF n8n: Git Node fetch/pull/pushTags Operations Bypass Sandbox Path Restriction

Impact Authenticated 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 th...

n8n: SSO Instance-Role Provisioning Allows Privilege Escalation to Instance Owner

Impact n8n's Enterprise SSO instance-role provisioning maps a role claim asserted by the configured Identity Provider IdP to an n8n global role and applies it during authentication. The provisioning path did not prevent assignment of the global:owner role, unlike the token-exchange identity path,...
