Flowise is a drag & drop user interface to build a customized large language model flow. In version 3.0.5 and earlier, the `forgot-password` endpoint in Flowise returns sensitive information including a valid password reset `tempToken` without authentication or verification. This enables any attacker to generate a reset token for arbitrary users and directly reset their password, leading to a complete account takeover (ATO). This vulnerability applies to both the cloud service (`cloud.flowiseai.com`) and self-hosted/local Flowise deployments that expose the same API. Commit 9e178d68873eb876073846433a596590d3d9c863 in version 3.0.6 secures password reset endpoints. Several recommended remediation steps are available. Do not return reset tokens or sensitive account details in API responses. Tokens must only be delivered securely via the registered email channel. Ensure `forgot-password` responds with a generic success message regardless of input, to avoid user enumeration. Require strong validation of the `tempToken` (e.g., single-use, short expiry, tied to request origin, validated against email delivery). Apply the same fixes to both cloud and self-hosted/local deployments. Log and monitor password reset requests for suspicious activity. Consider multi-factor verification for sensitive accounts.

According to its banner, the version of Flowise running on the remote host is < 3.0.6. It is, therefore, affected by multiple vulnerabilities :

- An Unauthenticated Password Reset Token Disclosure

- A Server-Side Request Forgery vulnerability in the /api/v1/fetch-links endpoint

- A Remote Code Execution through CustomMCP node

- An unauthenticated Arbitrary File Read vulnerability through the chatId parameter supplied to both the /api/v1/get-upload-file and /api/v1/openai-assistants-file/download endpoints

- A Remote Code Execution through the Supabase RPC Filter component

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.
