n8n: External Secrets Accessible via Workflow Expressions Outside Credentials

Impact External secrets were incorrectly resolved in workflow node expressions, where they are not intended to be available. An authenticated user with project editor access could read the plaintext value of external secrets by referencing them in a node expression, without needing explicit secre...

GHSA-CJ9H-QX8G-PQ2G n8n: Shared-Workflow Editor Can Exfiltrate Credentials via Inline Sub-Workflow JSON

Impact n8n's credential-access checks validated only a node's top-level credentials, not credentials referenced inside an Execute Sub-workflow node's inline workflow JSON. A member with editor access to a shared workflow could reference a credential they were not permitted to use inside that inli...

Incorrect Authorization

Overview @n8n/n8n-nodes-langchain is a Affected versions of this package are vulnerable to Incorrect Authorization via the Execute Sub-workflow. An attacker can access unauthorized credentials by referencing credential IDs within inline workflow JSON, bypassing intended access controls. Note: Thi...

GHSA-VHF8-CG2H-CG3P 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...

GHSA-PM35-FQVH-CQ5G n8n: Legacy Expression Evaluator Sanitizer Bypass Leads to Authenticated Code Execution

Impact The legacy expression evaluator's computed-member sanitizer can be bypassed by an authenticated user with workflow create or modify permissions. Successful exploitation grants the attacker host-level code execution as the n8n process. The legacy expression engine is the default engine in...

Server-side Request Forgery (SSRF)

Overview n8n is a n8n Workflow Automation Tool Affected versions of this package are vulnerable to Server-side Request Forgery SSRF in the /rest/dynamic-node-parameters/ endpoint due to insufficient authorization checks and the ability to supply an absolute URL in the routing configuration. An...

n8n: "Allowed HTTP Request Domains" Restriction Bypass via AI Agents MCP Connector

Impact The AI Agents feature did not enforce the "Allowed HTTP Request Domains" restriction configured on credentials. As a result, a member-level user who had been granted use-only access to a shared credential could cause its secret to be sent to an external server they control, by pointing an...
