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 · high confidence

The Mendix Forgot Password Appstore module versions prior to V3.2.1 contains an improper access control vulnerability in the password reset flow. An attacker can exploit this flaw to bypass authorization checks during the forgot password process, allowing them to reset arbitrary user passwords and take over accounts.

MitigationUpdate the Mendix Forgot Password module to version V3.2.1 or later from the Mendix Appstore, then thoroughly test the password reset functionality to confirm the fix works correctly and does not introduce regressions.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Locate the Forgot Password module in your Mendix project
    Open your Mendix project in the Mendix Modeler (Studio Pro) and navigate to the Project Explorer. Look for a module named 'ForgotPassword', 'Forgot Password', or similar in the App Store modules section.
    Affected if The Forgot Password module from the Mendix Appstore is present in your project
  2. Determine the installed version of the Forgot Password module
    Right-click on the Forgot Password module in the Project Explorer and select 'Module settings' or 'Properties'. Alternatively, check the module's .mpk file properties if you have the exported module. Look for a version number field.
    Affected if The version displayed is lower than 3.2.1 (e.g., 3.2.0, 3.1.x, 3.0.x, etc.)
  3. Verify the password reset microflow is in use
    In the Mendix Modeler, check your app's navigation or security settings to see if the 'ForgotPassword' microflow or page is exposed as part of your authentication flow, typically accessible via the login page.
    Affected if The Forgot Password flow is enabled and accessible to unauthenticated users through your application's public pages

You are affected if the Mendix Forgot Password module version is below 3.2.1 and the password reset functionality is exposed in your application.
