CVE-2025-3709
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAgentflow from Flowring Technology has an Account Lockout Bypass vulnerability, allowing unauthenticated remote attackers to exploit this vulnerability to perform password brute force attack.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceAgentflow from Flowring Technology contains an Account Lockout Bypass vulnerability that allows unauthenticated remote attackers to circumvent built-in account lockout mechanisms. This enables persistent password brute force attacks against the authentication system without triggering lockout protections.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm Flowring Agentflow is installedLocate the Agentflow installation directory or check system inventory for 'Flowring Agentflow' softwareAffected if Agentflow software is not found in the environment, the system is not applicable to this CVE
-
Identify installed Agentflow versionAccess the Agentflow administration panel or check installation files for the version number (typically found in About, System Info, or version metadata files)Affected if The installed version is exactly 4.0 - this is the only affected version per the CVE advisory
-
Verify web-based authentication is enabledCheck Agentflow configuration settings for authentication module status or test access to the login endpointAffected if The authentication interface is disabled or not accessible, the lockout bypass cannot be exploited
-
Confirm account lockout policy is configuredReview Agentflow security settings to verify if account lockout after failed attempts is enabledAffected if Lockout policies are not configured, the built-in lockout mechanism the bypass targets is not in use
The environment is affected if Flowring Agentflow version 4.0 is installed with authentication enabled and account lockout policies configured.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement account lockout enforcement with progressive delays, enforce multi-factor authentication, and add CAPTCHA or IP-based rate limiting to prevent automated brute force attempts.
