GHSA-3875-8GCX-7V46
Vulnerability from github – Published: 2026-05-19 16:17 – Updated: 2026-07-20 13:34Impact
The POST /rest/dynamic-node-parameters/options endpoint allowed any authenticated user to cause the n8n server to issue HTTP requests including credentials bypassing the intended restrictions on which hosts could be contacted for that credential (Allowed HTTP Request Domains). The user needed to be authenticated and have access to the credential.
Patches
The issue has been fixed in n8n version 2.20.0. Users should upgrade to this version or later to remediate the vulnerability.
Workarounds
If upgrading is not immediately possible, administrators should consider the following temporary mitigations: - Restrict n8n access to fully trusted users only. - Limit credential sharing to users who genuinely require access to those credentials.
These workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.

CAPEC-664: Server Side Request Forgery
An adversary exploits improper input validation by submitting maliciously crafted input to a target application running on a server, with the goal of forcing the server to make a request either to itself, to web services running in the server’s internal network, or to external third parties. If successful, the adversary’s request will be made with the server’s privilege level, bypassing its authentication controls. This ultimately allows the adversary to access sensitive data, execute commands on the server’s network, and make external requests with the stolen identity of the server. Server Side Request Forgery attacks differ from Cross Site Request Forgery attacks in that they target the server itself, whereas CSRF attacks exploit an insecure user authentication mechanism to perform unauthorized actions on the user's behalf.
