CVE-2025-3709Network attack vector

Unauthenticated password brute force via lockout bypass

Published May 2, 2025 · Updated May 2, 2025

Account lockout bypass in Flowring Technology Agentflow 4.0 allows remote attackers to perform password brute-force attacks. TWCERT/CC does not identify the affected authentication endpoint or explain how Agentflow fails to enforce the failed-attempt limit. No authentication or user interaction is required; repeated password guesses can compromise accounts whose credentials are discovered.
