The public OIDC login and callback endpoints ran the full flow whether or not OIDC was the instance's active, enabled authentication method, so turning OIDC off in Settings did not stop it issuing sessions. An administrator who disabled the provider still had a working login route. The patch requires OIDC to be the enabled, active authentication method before either endpoint starts the flow or issues a session.
The issue affects n8n Enterprise instances where OIDC was configured at least once and subsequently disabled.
The issue has been fixed in n8n versions 1.123.76, 2.37.7, and 2.38.2. Users should upgrade to one of these versions or later to remediate the vulnerability.
If upgrading is not immediately possible, administrators should consider the following temporary mitigations:
These workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.
