CWE-639
Weakness 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.
It is likely that an attacker would have to be an authenticated user in the system. However, the authorization process would not properly check the data access operation to ensure that the authenticated user performing the operation has sufficient entitlements to perform the requested data access, hence bypassing any other authorization checks present in the system.
For example, attackers can look at places where user specific data is retrieved (e.g. search screens) and determine whether the key for the item being looked up is controllable externally. The key may be a hidden field in the HTML form field, might be passed as a URL parameter or as an unencrypted cookie variable, then in each of these cases it will be possible to tamper with the key value.
Mapping guidance
This CWE entry is at the Base level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.
Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.
Relationships and members
Modes of introduction
REALIZATION: This weakness is caused during implementation of an architectural security tactic.
Retrieval of a user record occurs in the system based on some key value that is under user control. The key would typically identify a user-related record stored in the system and would be used to lookup that record for presentation to the user.
One manifestation of this weakness is when a system uses sequential or otherwise easily-guessable session IDs that would allow one user to easily switch to another user's session and read/modify their data.
Detection methods
Automated Static Analysis
Automated static analysis, commonly referred to as Static Application Security Testing (SAST), can find some instances of this weakness by analyzing source code (or binary/compiled code) without having to execute it. Typically, this is done by building a model of data flow and control flow, then searching for potentially-vulnerable patterns that connect "sources" (origins of input) with "sinks" (destinations where the data interacts with external components, a lower layer such as the OS, etc.)
Effectiveness: High
Notes
Maintenance
As of CWE 4.20, the relationship between IDOR and BOLA needs to be investigated more closely, including research into how these terms are used in the industry. The CWE team suspects that IDOR can be a part of BOLA, but BOLA expands on the weakness inherent to IDOR in that it is not only about objects that are being directly referenced.

GHSA-35Q8-9MJ6-WJMF
Vulnerability from github – Published: 2026-07-22 22:04 – Updated: 2026-07-22 22:04Impact
n8n's Enterprise SSO instance-role provisioning maps a role claim asserted by the configured Identity Provider (IdP) to an n8n global role and applies it during authentication. The provisioning path did not prevent assignment of the global:owner role, unlike the token-exchange identity path, which explicitly rejects it. As a result, an SSO-authenticated user whose instance-role claim resolves to global:owner is provisioned as an instance owner, obtaining full administrative control over all workflows, credentials, users, and instance configuration.
This is a privilege-escalation issue that is exploitable only under specific conditions. It affects instances where Enterprise SSO is configured and instance-role provisioning is enabled via the N8N_SSO_SCOPES_PROVISION_INSTANCE_ROLE flag, which is disabled by default. Exploitation additionally requires the attacker to control the value of the instance-role claim issued by the IdP. As this claim is typically an administrator-managed attribute, exploitation generally requires control over the IdP or its claim-to-role mapping, or a permissive IdP configuration in which a lower-privileged user can influence the claim value. Deployments that do not use Enterprise SSO, or that have instance-role provisioning disabled, are not affected.
Patches
The issue has been fixed in n8n versions 1.123.64, 2.29.8, and 2.30.1. 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:
- Disable instance-role provisioning by unsetting or setting N8N_SSO_SCOPES_PROVISION_INSTANCE_ROLE=false.
- Audit IdP claim mappings to ensure no user-controllable attribute can supply the instance-role claim value.
- Restrict SSO access to fully trusted users only.
These workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.

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.
No CAPEC attack patterns related to this CWE.
