Introduction

FlowiseAI, a rising star in AI workflow orchestration and LLM agent building, has been hit by a critical security flaw: CVE-2025-58434.

This vulnerability allows unauthenticated attackers to obtain valid password reset tokens simply by submitting a victim’s email to the public API. With the token, attackers can reset any account’s password — including administrators — leading to full account takeover (ATO).

 Vulnerability Summary

• CVE ID: CVE-2025-58434
• Affected Versions: Flowise ≤ 3.0.5
• Patched Version: 3.0.5+ (fixed in latest release)
• CVSS v3.1 Base Score: 9.8 Critical
• Attack Vector: Network (no authentication required)
• Impact: Full account takeover, integrity compromise, workflow manipulation, sensitive data theft

 Technical Exploitation Path

Step 1 — Obtain Reset Token

Send a POST request to:

/api/v1/account/forgot-password

with victim’s email address.

 The API response incorrectly includes a tempToken, user ID, and other details.

Step 2 — Reset Password

Use the tempToken in:

/api/v1/account/reset-password

to set a new password for the victim.

Step 3 — Log In as Victim

Now the attacker logs in with the new password → complete compromise.

 Why It’s So Dangerous

1. No Verification Step — reset token should be emailed, but instead it’s returned directly.
2. User Enumeration Risk — attackers learn which emails exist.
3. Admin Takeover — single exploit can compromise entire Flowise deployment.
4. Cloud & Self-Hosted Both Affected — any exposed API endpoint is exploitable.

 Global Impact

• Enterprises using Flowise Cloud → Risk of LLM workflow manipulation and data theft.
• Self-hosted deployments → Attackers can hijack accounts, inject malicious nodes, exfiltrate data.
• AI-driven SOCs & DevOps teams → Attackers may plant backdoors into automated flows.
• Regulatory Risk → GDPR, HIPAA, PCI-DSS violations if customer data processed via Flowise is exposed.

 CyberDudeBivash Recommendations

1. Patch Immediately — Upgrade to Flowise v3.0.5+.
2. Harden Password Reset Workflow — Tokens must only be sent via email, never returned in API.
3. Restrict API Access — Protect forgot/reset endpoints with rate limiting & WAF rules.
4. Enable MFA — Reduce risk even if passwords are compromised.
5. Monitor Logs — Watch for abnormal password reset attempts.
6. Penetration Test APIs — Regularly audit all auth flows for insecure designs.

 Future Outlook

• Expect automated scanners to hunt Flowise instances online.
• Proof-of-concepts will appear in exploit databases.
• This flaw highlights the criticality of secure-by-design API authentication in AI/LLM platforms.
• Similar SaaS/AI startups will face increased penetration testing scrutiny.

 Conclusion

The FlowiseAI Password Reset Token Vulnerability (CVE-2025-58434) is a textbook critical ATO flaw caused by unsafe password reset design.

Any organization running vulnerable FlowiseAI must patch immediately. Failure to do so could mean full account compromise, workflow tampering, and regulatory nightmares.
