CWE-639
AllowedAuthorization Bypass Through User-Controlled Key
Abstraction: Base · Status: Incomplete
The system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data.
4780 vulnerabilities reference this CWE, most recent first.
GHSA-M63J-689W-3J35
Vulnerability from github – Published: 2026-03-25 21:08 – Updated: 2026-03-25 21:08Impact
An authenticated user with the global:member role could exploit chained authorization flaws in n8n's credential pipeline to steal plaintext secrets from generic HTTP credentials (httpBasicAuth, httpHeaderAuth, httpQueryAuth) belonging to other users on the same instance.
The attack abuses a name-based credential resolution path that does not enforce ownership or project scope, combined with a bypass in the credentials permission checker that causes generic HTTP credential types to be skipped during pre-execution validation. Together, these flaws allow a member-role user to resolve another user's credential ID and execute a workflow that decrypts and uses that credential without authorization.
Native integration credential types (e.g. slackApi, openAiApi, postgres) are not affected by this issue.
This vulnerability affects Community Edition only. Enterprise Edition has additional permission gates on workflow creation and execution that independently block this attack chain.
Patches
The issue has been fixed in n8n versions 1.123.27, 2.13.3, and 2.14.1. Users should upgrade to one of these versions or later to remediate the vulnerability.
Workarounds
If upgrading is not immediately possible, administrators should consider the following temporary mitigations:
- Restrict instance access to fully trusted users only.
- Audit credentials stored on the instance and rotate any generic HTTP credentials (httpBasicAuth, httpHeaderAuth, httpQueryAuth) that may have been exposed.
These workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.

Vulnerability from github – Published: 2026-07-28 00:31 – Updated: 2026-07-28 00:31The vulnerability involves an Insecure Direct Object Reference (IDOR) in the DeleteNotificationController::delete() method at endpoint GET /notification/delete/{id}. The flaw allows any authenticated user, regardless of company or permissions, to delete notifications belonging to any other user in the system. The controller retrieves the target record with Notification::findOrFail($id) and deletes it without validating user_id or company_id ownership, unlike the sibling SetNotificationReadAjaxController, which correctly scopes lookups by Auth::id(). Because notification identifiers are sequential, an attacker can iterate over IDs to systematically delete notifications belonging to any user, denying them visibility of ticket alerts, task assignments, and other system events.

Mitigation
For each and every data access, ensure that the user has sufficient privilege to access the record that is being requested.
Mitigation
Make sure that the key that is used in the lookup of a specific user's record is not controllable externally by the user or that any tampering can be detected.
Mitigation
Use encryption in order to make it more difficult to guess other legitimate values of the key or associate a digital signature with the key so that the server can verify that there has been no tampering.
