GHSA-5WXP-QJGQ-FX6M
Vulnerability from github – Published: 2026-05-14 14:54 – Updated: 2026-06-09 13:10Summary
A Mass Assignment vulnerability exists in the chatflow update endpoint of FlowiseAI.
The endpoint allows clients to modify server-controlled properties such as deployed, isPublic, workspaceId, createdDate, and updatedDate when updating a chatflow object.
Due to missing server-side validation and authorization checks, an authenticated user can manipulate internal attributes of a chatflow and reassign it to another workspace. This allows cross-workspace resource reassignment and unauthorized modification of deployment and visibility settings.
Details
The endpoint responsible for updating chatflows:
PUT /api/v1/chatflows/{chatflowId}
accepts a JSON request body containing the chatflow configuration (flowData) along with other metadata fields.
However, the server does not restrict which properties may be modified by the client. As a result, user-controlled request bodies can include additional fields that should normally be controlled only by the backend.
Examples of server-controlled fields that can be manipulated include:
- deployed
- isPublic
- workspaceId
- createdDate
- updatedDate
- category
- type
These fields appear to be directly mapped to the underlying database entity when processing the update request, suggesting that the server performs a direct merge of the request body into the chatflow model without applying a strict DTO whitelist or authorization checks.
For example, modifying the request body with:
{
"deployed": true,
"isPublic": true,
"createdDate": "1999-03-06T10:59:32.000Z",
"updatedDate": "1999-03-06T13:21:34.000Z",
"workspaceId": "11111111-2222-3333-4444-555555555555"
}
results in the server accepting and persisting these values.
In testing, a second workspace was created in the database and the workspaceId field was successfully modified through the API request. The chatflow was reassigned to the attacker-controlled workspace, confirming that the application does not enforce workspace ownership validation.
PoC
Authenticate to the Flowise interface.
Capture the request used to update a chatflow:
PUT /api/v1/chatflows/<CHATFLOW_ID>
Content-Type: application/json
Modify the request body by injecting additional fields:
{
"name": "test-flow",
"flowData": "{...}",
"deployed": true,
"isPublic": true,
"workspaceId": "11111111-2222-3333-4444-555555555555"
}
Send the request.
Observe that the response returns the manipulated values:
{
"deployed": true,
"isPublic": true,
"workspaceId": "11111111-2222-3333-4444-555555555555"
}
Verify in the database that the chatflow has been reassigned:
SELECT id, workspaceId FROM chat_flow WHERE id='<CHATFLOW_ID>';
The workspaceId value reflects the attacker-supplied workspace.
Impact
This vulnerability allows authenticated users to manipulate server-controlled attributes of chatflows.
Confirmed impacts include:
- Unauthorized modification of chatflow visibility (isPublic)
- Unauthorized deployment state changes (deployed)
- Cross-workspace reassignment of chatflows (workspaceId)
- Unauthorized modification of metadata (createdDate, updatedDate)
In multi-tenant environments, this allows an attacker to move chatflows between workspaces without authorization, breaking tenant isolation boundaries.
This may enable:
- Cross-workspace workflow takeover
- Unauthorized exposure of private workflows
- Manipulation of deployed agent workflows
The issue stems from missing authorization checks and improper handling of client-controlled input in the chatflow update endpoint.

Mitigation MIT-1
Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
Mitigation MIT-46
Strategy: Separation of Privilege
- Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
- Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
CAPEC-19: Embedding Scripts within Scripts
An adversary leverages the capability to execute their own script by embedding it within other scripts that the target software is likely to execute due to programs' vulnerabilities that are brought on by allowing remote hosts to execute scripts.
CAPEC-441: Malicious Logic Insertion
An adversary installs or adds malicious logic (also known as malware) into a seemingly benign component of a fielded system. This logic is often hidden from the user of the system and works behind the scenes to achieve negative impacts. With the proliferation of mass digital storage and inexpensive multimedia devices, Bluetooth and 802.11 support, new attack vectors for spreading malware are emerging for things we once thought of as innocuous greeting cards, picture frames, or digital projectors. This pattern of attack focuses on systems already fielded and used in operation as opposed to systems and their components that are still under development and part of the supply chain.
CAPEC-478: Modification of Windows Service Configuration
An adversary exploits a weakness in access control to modify the execution parameters of a Windows service. The goal of this attack is to execute a malicious binary in place of an existing service.
CAPEC-479: Malicious Root Certificate
An adversary exploits a weakness in authorization and installs a new root certificate on a compromised system. Certificates are commonly used for establishing secure TLS/SSL communications within a web browser. When a user attempts to browse a website that presents a certificate that is not trusted an error message will be displayed to warn the user of the security risk. Depending on the security settings, the browser may not allow the user to establish a connection to the website. Adversaries have used this technique to avoid security warnings prompting users when compromised systems connect over HTTPS to adversary controlled web servers that spoof legitimate websites in order to collect login credentials.
CAPEC-502: Intent Spoof
An adversary, through a previously installed malicious application, issues an intent directed toward a specific trusted application's component in an attempt to achieve a variety of different objectives including modification of data, information disclosure, and data injection. Components that have been unintentionally exported and made public are subject to this type of an attack. If the component trusts the intent's action without verififcation, then the target application performs the functionality at the adversary's request, helping the adversary achieve the desired negative technical impact.
CAPEC-503: WebView Exposure
An adversary, through a malicious web page, accesses application specific functionality by leveraging interfaces registered through WebView's addJavascriptInterface API. Once an interface is registered to WebView through addJavascriptInterface, it becomes global and all pages loaded in the WebView can call this interface.
CAPEC-536: Data Injected During Configuration
An attacker with access to data files and processes on a victim's system injects malicious data into critical operational data during configuration or recalibration, causing the victim's system to perform in a suboptimal manner that benefits the adversary.
CAPEC-546: Incomplete Data Deletion in a Multi-Tenant Environment
An adversary obtains unauthorized information due to insecure or incomplete data deletion in a multi-tenant environment. If a cloud provider fails to completely delete storage and data from former cloud tenants' systems/resources, once these resources are allocated to new, potentially malicious tenants, the latter can probe the provided resources for sensitive information still there.
CAPEC-550: Install New Service
When an operating system starts, it also starts programs called services or daemons. Adversaries may install a new service which will be executed at startup (on a Windows system, by modifying the registry). The service name may be disguised by using a name from a related operating system or benign software. Services are usually run with elevated privileges.
CAPEC-551: Modify Existing Service
When an operating system starts, it also starts programs called services or daemons. Modifying existing services may break existing services or may enable services that are disabled/not commonly used.
CAPEC-552: Install Rootkit
An adversary exploits a weakness in authentication to install malware that alters the functionality and information provide by targeted operating system API calls. Often referred to as rootkits, it is often used to hide the presence of programs, files, network connections, services, drivers, and other system components.
CAPEC-556: Replace File Extension Handlers
When a file is opened, its file handler is checked to determine which program opens the file. File handlers are configuration properties of many operating systems. Applications can modify the file handler for a given file extension to call an arbitrary program when a file with the given extension is opened.
CAPEC-558: Replace Trusted Executable
An adversary exploits weaknesses in privilege management or access control to replace a trusted executable with a malicious version and enable the execution of malware when that trusted executable is called.
CAPEC-562: Modify Shared File
An adversary manipulates the files in a shared location by adding malicious programs, scripts, or exploit code to valid content. Once a user opens the shared content, the tainted content is executed.
CAPEC-563: Add Malicious File to Shared Webroot
An adversaries may add malicious content to a website through the open file share and then browse to that content with a web browser to cause the server to execute the content. The malicious content will typically run under the context and permissions of the web server process, often resulting in local system or administrative privileges depending on how the web server is configured.
CAPEC-564: Run Software at Logon
Operating system allows logon scripts to be run whenever a specific user or users logon to a system. If adversaries can access these scripts, they may insert additional code into the logon script. This code can allow them to maintain persistence or move laterally within an enclave because it is executed every time the affected user or users logon to a computer. Modifying logon scripts can effectively bypass workstation and enclave firewalls. Depending on the access configuration of the logon scripts, either local credentials or a remote administrative account may be necessary.
CAPEC-578: Disable Security Software
An adversary exploits a weakness in access control to disable security tools so that detection does not occur. This can take the form of killing processes, deleting registry keys so that tools do not start at run time, deleting log files, or other methods.
