GHSA-XMC9-4F2H-JF9C n8n: Edit Image Node Format Injection Allows Arbitrary File Write

Impact The n8n Edit Image node passed its output format to the underlying image library without validation, so a crafted value could write bytes to a location outside the node's working directory. An authenticated user able to run workflows could use this to write arbitrary files in the n8n...

External Control of File Name or Path

Overview n8n-nodes-base is a Base nodes of n8n Affected versions of this package are vulnerable to External Control of File Name or Path via the Edit Image. An attacker can write arbitrary files outside the intended directory by supplying crafted values to the output format parameter. Workaround...

n8n: Credential Authorization Bypass via Expression in HTTP Request Node `genericAuthType`

Impact An authenticated member with edit access to a shared workflow could reference another user's credential in an HTTP Request node while specifying the credential type through an expression. Because the pre-execution permission check compared the unresolved expression instead of the real...

Incorrect Authorization

Overview n8n is a n8n Workflow Automation Tool Affected versions of this package are vulnerable to Incorrect Authorization via the genericAuthType in the HTTP Request node. An attacker can gain unauthorized access to credentials belonging to other users by referencing another user's credential...

GHSA-RCV6-PVRJ-4XCG n8n: Authenticated code execution in the n8n Git node

Impact Authenticated n8n users with rights to create and execute workflows could achieve code execution on the n8n host. Using the Git node, under the default git security settings, by staging a crafted local repository, an attacker could cause git to run hooks, executing arbitrary commands as th...

Command Injection

Overview n8n-nodes-base is a Base nodes of n8n Affected versions of this package are vulnerable to Command Injection via the Git node. An attacker can execute arbitrary commands as the application process user by crafting a local repository to trigger git hooks during workflow execution. Note: Th...

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...

Server-side Request Forgery (SSRF)

Overview @n8n/n8n-nodes-langchain is a Affected versions of this package are vulnerable to Server-side Request Forgery SSRF in the MCP Client. An attacker can access internal or otherwise restricted network resources by supplying crafted endpoints, causing the server to connect to unintended host...

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-H44J-F5R5-PH73 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...

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...
