Impact
An authenticated user signed in through Single Sign-On (SSO) could disable SSO enforcement for their own account through the n8n API. This allowed the user to create a local password and authenticate directly with email and password, completely bypassing the organization's SSO policy, centralized identity management, and any identity-provider-enforced multi-factor authentication.
Patches
The issue has been fixed in n8n version 2.8.0. 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:
- Monitor audit logs for users who create local credentials after authenticating via SSO.
- Restrict the n8n instance to fully trusted users only.
These workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.
The vulnerability can be exploited over the network without needing physical access. It is difficult for an attacker to exploit this vulnerability and may require special conditions. An attacker needs basic access or low-level privileges. No user interaction is needed for the attacker to exploit this vulnerability. The vulnerability can affect other systems as well, not just the initial system. There is a high impact on the integrity of the data.
Exploitation attempts have been detected. Elevated vigilance and prompt remediation are advised.
The exploit probability is very low. The vulnerability is unlikely to be exploited in the next 30 days.
We did not find any exploit available. Neither in GitHub repositories nor in the Exploit-Database.
