EUVD-2025-210336

Flowise before 3.0.6 contains an arbitrary file read vulnerability in the chatId parameter of the /api/v1/get-upload-file and /api/v1/openai-assistants-file/download endpoints. The chatId value is not validated and is passed to streamStorageFile, where a fallback file-lookup path constructed...

EUVD-2025-210337

Flowise contains an authentication bypass vulnerability in the unprotected /api/v1/account/register endpoint that allows unauthenticated attackers to create user accounts. Remote attackers can exploit this endpoint to register arbitrary accounts and authenticate to the system, gaining full API...

EUVD-2025-210338

Flowise before 3.0.10 contains an unverified password change vulnerability. An authenticated user can change their account password through the account settings Security section without supplying the current password or any additional verification, as the application does not enforce a...

CVE-2025-71338

Flowise is affected by a path traversal vulnerability in the /api/v1/document-store/loader/process endpoint that allows unauthenticated attackers to write arbitrary files to the filesystem by crafting unsanitized fileName parameters with ../ sequences. This can overwrite critical files (e.g., pac...

CVE-2025-71335

Flowise prior to version 3.0.10 is affected. Versions 3.0.7 and earlier do not invalidate existing sessions or session tokens after a user changes their password, allowing an attacker with an active session (e.g., via a stolen token or an already-logged-in device) to remain authenticated post-pas...

CVE-2025-71336

Flowise vulnerability: Unsandboxed remote code execution in Custom MCP. Affected: Flowise before 3.0.6 (2.2.7-patch.1 and earlier). Attack requires crafting a JSON payload and header x-request-from: internal to /api/v1/node-load-method/customMCP, taking advantage of minimal auth to execute OS com...

CVE-2025-71334

Flowise before 3.0.6 (affected versions 2.2.8 and earlier) contains an arbitrary file access vulnerability due to missing validation that chatflowId and chatId are UUIDs or numbers in file handling. An attacker can use path traversal (e.g., ../../../../../tmp) via /api/v1/chatflows (addBase64File...

CVE-2025-71327

Flowise has an authentication bypass in the unprotected /api/v1/account/register endpoint. Unauthenticated attackers can register arbitrary accounts and gain full API access without credentials. CVSS metrics are provided (v3.1: 9.1; v4.0: 9.3), indicating a critical impact on confidentiality and ...

CVE-2025-71324

Flowise before 3.0.6 has an arbitrary file-read vulnerability in the chatId parameter of /api/v1/get-upload-file and /api/v1/openai-assistants-file/download. The chatId value is not validated and is passed to streamStorageFile(), where a fallback file-lookup path constructed without the orgId is ...

Flowise 1.4.3 - Arbitrary File Read

Flowise 1.4.3 contains a path traversal caused by lack of sanitization of 'fileName' parameter in /api/v1/openai-assistants-file endpoint in index.ts, letting attackers read arbitrary files, exploit requires attacker to send crafted request. id: CVE-2024-36420 info: name: Flowise 1.4.3 - Arbitrar...

Flowise <= 1.8.2 Authentication Bypass

An Authentication Bypass vulnerability exists in Flowise version 1.8.2. This could allow a remote, unauthenticated attacker to access API endpoints as an administrator and allow them to access restricted functionality. id: CVE-2024-8181 info: name: Flowise = 1.8.2 Authentication Bypass author:...

Flowise - NVIDIA NIM Endpoints Missing Authentication

Flowise is a drag & drop user interface to build a customized large language model flow.

Flowise <= 3.0.5 - Account Takeover

Flowise versions 3.0.5 and earlier had a vulnerability in the forgot-password endpoint, which returned valid reset tokens without authentication—allowing attackers to reset passwords and take over accounts. id: CVE-2025-58434 info: name: Flowise = 3.0.5 - Account Takeover author:...

Flowise - Remote Code Execution

Flowise 3.0.5 contains a remote code execution vulnerability caused by unsafe evaluation of user input in the CustomMCP node's convertToValidJSONString function, letting remote attackers execute arbitrary code with full Node.js privileges, exploit requires user input to be processed by the...

Flowise < 3.0.1 - Remote Command Execution

The Custom MCPs feature is designed to execute OS commands, for instance, using tools like npx to spin up local MCP Servers. However, Flowise's inherent authentication and authorization model is minimal and lacks role-based access controls RBAC. Furthermore, in Flowise versions before 3.0.1 the...
