n8n: SSRF Protection Bypass via MCP Client Node

Impact On an n8n instance with SSRF protection enabled, the MCP Client node sent requests to a user-supplied endpoint without routing them through that protection and without pinning the resolved address. An authenticated user who could create or edit a workflow could therefore cause the server t...

Directory Traversal

Overview n8n-nodes-base is a Base nodes of n8n Affected versions of this package are vulnerable to Directory Traversal via the Git node's fetch, pull, or push-tags operations. An attacker can access files and history outside the intended workspace by configuring an allowlisted remote value to poi...

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...

GHSA-P3RG-HRF9-W9GJ n8n: DOM-Based XSS via Unsandboxed iframe srcdoc in HTML Preview

Impact The HTML preview renders execution output into an iframe srcdoc without sandbox, so a sanitizer bypass lets injected script run same-origin as the editor. When a victim opens the preview, it can call authenticated APIs with their session. An account with global:member privileges can exploi...

n8n: Race Condition in Git Clone Node Allows Authenticated Users to Achieve Remote Code Execution

Impact A TOCTOU race condition in the Git node's clone operation lets an authenticated user bypass its path restrictions by swapping a directory for a symlink after the path is validated but before the clone runs. This plants a crafted repository in the community node directory, which n8n loads a...
