GHSA-V5W9-PRXF-W882
Vulnerability from github – Published: 2025-11-17 19:06 – Updated: 2025-11-17 19:06Summary
An unauthenticated attacker can exploit the unprotected registration endpoint (/register) to create a new user and bypass authentication.
Details
Critical vulnerability in Flowise 3.0.1 on-premise deployment allows unauthenticated attackers to exploit the /api/v1/account/register endpoint to add a new user and log in using it, enabling authentication bypass.
Meaning that the register functionality is by default open, allowing attackers to create an account and use the api without any restrictions or credentials.
PoC
A Flowise 3.0.1 instance was deployed via Docker for the purpose of this demonstration.
After successful deployment the instance setup organization page allows us to register the first account in the system.
Creating the first user research@evasec.io
Login to the account
The background request that created the first user to /api/v1/account/register
Response
We have found that it is possible to reuse the registration request multiple times without any restrictions to create an account and authenticate to the system using it.
Crafting a new request
{
"user": {
"name": "Malicious",
"email": "attacker@attack.io",
"type": "pro",
"credential": "Password123!"
}
}
Response with 201 code “Created”
Login using newly created user (attacker)
Success login
An unauthorized user can exploit this vulnerability to register an account and gain access to the Flowise API with authenticated privileges, effectively bypassing authentication.
Impact
This is an authentication bypass vulnerability caused by an unprotected registration endpoint (/register).
Users of Flowise 3.0.1(latest) on-premise deployments are impacted. An unauthorized attacker can exploit this vulnerability to register an account after the organization set has been completed, and gain access to the Flowise API with authenticated privileges, effectively bypassing authentication.

The vulnerability is due to a logic error that may occur when certain sequences of actions are processed during an SSH login event on the affected device. An attacker could exploit this vulnerability by initiating an SSH session to the device with a specific sequence that presents the two usernames. A successful exploit could result in logging data misrepresentation, user enumeration, or, in certain circumstances, a command authorization bypass. See the Details section for more information.

Mitigation
Strategy: Libraries or Frameworks
Use an authentication framework or library such as the OWASP ESAPI Authentication feature.
CAPEC-114: Authentication Abuse
An attacker obtains unauthorized access to an application, service or device either through knowledge of the inherent weaknesses of an authentication mechanism, or by exploiting a flaw in the authentication scheme's implementation. In such an attack an authentication mechanism is functioning but a carefully controlled sequence of events causes the mechanism to grant access to the attacker.
CAPEC-115: Authentication Bypass
An attacker gains access to application, service, or device with the privileges of an authorized or privileged user by evading or circumventing an authentication mechanism. The attacker is therefore able to access protected data without authentication ever having taken place.
CAPEC-151: Identity Spoofing
Identity Spoofing refers to the action of assuming (i.e., taking on) the identity of some other entity (human or non-human) and then using that identity to accomplish a goal. An adversary may craft messages that appear to come from a different principle or use stolen / spoofed authentication credentials.
CAPEC-194: Fake the Source of Data
An adversary takes advantage of improper authentication to provide data or services under a falsified identity. The purpose of using the falsified identity may be to prevent traceability of the provided data or to assume the rights granted to another individual. One of the simplest forms of this attack would be the creation of an email message with a modified "From" field in order to appear that the message was sent from someone other than the actual sender. The root of the attack (in this case the email system) fails to properly authenticate the source and this results in the reader incorrectly performing the instructed action. Results of the attack vary depending on the details of the attack, but common results include privilege escalation, obfuscation of other attacks, and data corruption/manipulation.
CAPEC-22: Exploiting Trust in Client
An attack of this type exploits vulnerabilities in client/server communication channel authentication and data integrity. It leverages the implicit trust a server places in the client, or more importantly, that which the server believes is the client. An attacker executes this type of attack by communicating directly with the server where the server believes it is communicating only with a valid client. There are numerous variations of this type of attack.
CAPEC-57: Utilizing REST's Trust in the System Resource to Obtain Sensitive Data
This attack utilizes a REST(REpresentational State Transfer)-style applications' trust in the system resources and environment to obtain sensitive data once SSL is terminated.
CAPEC-593: Session Hijacking
This type of attack involves an adversary that exploits weaknesses in an application's use of sessions in performing authentication. The adversary is able to steal or manipulate an active session and use it to gain unathorized access to the application.
CAPEC-633: Token Impersonation
An adversary exploits a weakness in authentication to create an access token (or equivalent) that impersonates a different entity, and then associates a process/thread to that that impersonated token. This action causes a downstream user to make a decision or take action that is based on the assumed identity, and not the response that blocks the adversary.
CAPEC-650: Upload a Web Shell to a Web Server
By exploiting insufficient permissions, it is possible to upload a web shell to a web server in such a way that it can be executed remotely. This shell can have various capabilities, thereby acting as a "gateway" to the underlying web server. The shell might execute at the higher permission level of the web server, providing the ability the execute malicious code at elevated levels.
CAPEC-94: Adversary in the Middle (AiTM)
An adversary targets the communication between two components (typically client and server), in order to alter or obtain data from transactions. A general approach entails the adversary placing themself within the communication channel between the two components.
