n8n before 2.33.4 and 2.34.x before 2.34.1 contain a remote code execution vulnerability in the @n8n/workflow-sdk node-schema loader used for MCP node-schema loading. The loader derives a node's schema module path directly from the attacker-supplied node type string without validating...

n8n: GraphQL Node Bypasses "Allowed HTTP Request Domains" Restriction

Impact The GraphQL node did not enforce the "Allowed HTTP Request Domains" restriction on HTTP-based credentials such as Header Auth, Basic Auth, Query Auth, and OAuth, unlike the HTTP Request node. An authenticated user able to create or edit workflows could therefore point the node's endpoint a...

Arbitrary Code Injection

Overview n8n-workflow is a Workflow base code of n8n Affected versions of this package are vulnerable to Arbitrary Code Injection via crafted expressions using arrow functions in the expression. An attacker can execute arbitrary system commands by bypassing the intended sandbox restrictions. Note...

n8n: Stored DOM XSS via Resource Locator `cachedResultUrl`

Impact The Resource Locator passes the workflow-persisted cachedResultUrl to window.open without scheme validation. When a victim opens the crafted workflow and interact with external links, the JavaScript payload runs in the victim's browser. Patches The issue has been fixed in n8n versions...

Cross-site Scripting (XSS)

Overview n8n is a n8n Workflow Automation Tool Affected versions of this package are vulnerable to Cross-site Scripting XSS in the HTML preview, which renders execution output into an iframe srcdoc without the sandbox attribute. An attacker can execute arbitrary scripts in the context of the...
