    "summary": "Flowise has IDOR leading to Account Takeover and Enterprise Feature Bypass via SSO Configuration\nThe Flowise platform has a critical Insecure Direct Object Reference (IDOR) vulnerability combined with a Business Logic Flaw in the PUT /api/v1/loginmethod endpoint.\n\nWhile the endpoint requires authentication, it fails to validate if the authenticated user has ownership or administrative rights over the target organizationId. This allows any low-privileged user (including \"Free\" plan users) to:\n\n1. Overwrite the SSO configuration of any other organization.\n2. Enable \"Enterprise-only\" features (SSO/SAML) without a license.\n3. Perform Account Takeover  by redirecting the authentication flow.",
