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-XMVG-335G-X44Q
Vulnerability from github – Published: 2024-07-18 15:22 – Updated: 2024-07-18 15:22Summary
An issue in the OpenSearch reporting plugin allows unintended access to private tenant resources like notebooks. The system did not properly check if the user was the resource author when accessing resources in a private tenant, leading to potential data being revealed.
Impact
The lack of proper access control validation for private tenant resources in the OpenSearch observability and reporting plugins can lead to unintended data access. If an authorized user with observability or reporting roles is aware of another user's private tenant resource ID, such as a notebook, they can potentially read, modify, or take ownership of that resource, despite not being the original author, thus impacting the confidentiality and integrity of private tenant resources. The impact is confined to private tenant resources, where authorized users may gain inappropriate visibility into data intended to be private from other users within the same OpenSearch instance, potentially violating the intended separation of access. This issue does not alter the scope of access but highlights a flaw in the existing access control mechanisms.

Vulnerability from github – Published: 2022-05-24 17:22 – Updated: 2022-05-24 17:22An issue was discovered on various devices via the Linkplay firmware. There is WAN remote code execution without user interaction. An attacker could retrieve the AWS key from the firmware and obtain full control over Linkplay's AWS estate, including S3 buckets containing device firmware. When combined with an OS command injection vulnerability within the XML Parsing logic of the firmware update process, an attacker would be able to gain code execution on any device that attempted to update. Note that by default all devices tested had automatic updates enabled.

Vulnerability from github – Published: 2026-04-01 18:36 – Updated: 2026-07-21 14:59A writer role user in an attacker-controlled namespace could signal, delete, and reset workflows or activities in a victim namespace on the same cluster. Exploitation requires the attacker to know or guess specific victim workflow ID(s) and, for signal operations, signal names. This was due to a bug introduced in Temporal Server v1.29.0 which inadvertently allowed an attacker to control the namespace name value instead of using the server's own trusted name value within the batch activity code. The batch activity validated the namespace ID but did not cross-check the namespace name against the worker's bound namespace, allowing the per-namespace worker's privileged credentials to operate on an arbitrary namespace. Exploitation requires a server configuration where internal components have cross-namespace authorization, such as deployment of the internal-frontend service or equivalent TLS-based authorization for internal identities.
This vulnerability also impacted Temporal Cloud when the attacker and victim namespaces were on the same cell, with the same preconditions as self-hosted clusters.

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.
