n8n: Credential exfiltration via Allowed HTTP Request Domains Bypass
GitHub lists this reviewed advisory for n8n. Published version ranges and source prerequisites are shown below; this is not an inspection of a visitor’s application.
This report has not inspected your inventory, configuration, deployed build, reachability or evidence. A catalog listing and a severity score do not establish exposure or compromise.
01 / Meaning
Why it matters
Published affected context helps an owner decide what evidence to gather. This report has not examined your application.
9.1 medium
GitHub source severity; exploitability and local consequence require separate evidence.

02 / Applicability
The affected context
Affected versions, configuration prerequisites and known exclusions are public. Confirm each one against the deployed service.
n8n
source listed< 2.20.0
## Impact 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.
03 / Response
What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
04 / Limits
What this report cannot establish
- Customer inventory, deployment, reachability and exploitation have not been inspected.
05 / Provenance
Sources you can inspect
Each assertion retains its source. Mirrored records may repeat one underlying publisher; additional links are not independent corroboration.
