CVE-2025-58434

CVE-2025-58434: Flowise Cloud and Local Deployments have Unauthenticated Password Reset Token Disclosure that Leads to Account Takeover

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.

Root Cause Analysis

The vulnerability is a critical account takeover caused by the disclosure of a password reset token. The analysis of the provided security patch (commit 9e178d68873eb876073846433a596590d3d9c863) reveals the root cause and the affected functions.

The primary vulnerable function is AccountService.forgotPassword. The vulnerability description and the proof-of-concept show that the /api/v1/account/forgot-password endpoint returns a tempToken. The patch confirms this by showing that the return value of the forgotPassword function in packages/server/src/enterprise/services/account.service.ts was changed from return data to return sanitizeUser(data.user). The newly added sanitizeUser utility function removes sensitive fields like credential, tempToken, and tokenExpiry from the user object before it is sent in the response, thus fixing the information disclosure.

The AccountService.resetPassword function is also identified as relevant. An attacker uses this function with the leaked token to complete the account takeover. The patch also sanitizes the output of this function, indicating that it was also returning sensitive user information, which is a bad practice even if it wasn't the primary vulnerability. Both forgotPassword and resetPassword would be called during a successful exploitation of this vulnerability.

Therefore, the identified functions are the ones that would appear in a runtime profile when this vulnerability is triggered and exploited.
