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

September 12, 2025 (updated September 15, 2025)

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.
