    Incorrect Authorization

    @n8n/n8n-nodes-langchain is a Banner image

    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: This is only exploitable if workflow sharing is enabled and the attacker has been explicitly granted Editor access to a shared workflow, and knows the target credential's ID.

    How to fix Incorrect Authorization?

    Upgrade @n8n/n8n-nodes-langchain to version 1.122.46, 2.31.3, 2.32.1 or higher.

    Server-side Request Forgery (SSRF)

    @n8n/n8n-nodes-langchain is a Banner image

    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 hosts and return sensitive responses through workflow execution.

    Note: This is only exploitable if SSRF protection is enabled and the attacker has permissions to create or edit workflows.

    How to fix Server-side Request Forgery (SSRF)?

    Upgrade @n8n/n8n-nodes-langchain to version 2.31.3, 2.32.1 or higher.
