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 · unedited
The Flynax Bridge plugin for WordPress is vulnerable to privilege escalation via account takeover in all versions up to, and including, 2.2.0. This is due to the plugin not properly validating a user's identity prior to updating their details like password. This makes it possible for unauthenticated attackers to change arbitrary user's passwords, including administrators, and leverage that to gain access to their account.

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 Flynax Bridge plugin for WordPress (versions up to 2.2.0) lacks proper user identity validation before allowing password changes, enabling unauthenticated attackers to reset any user's password including administrator accounts and gain privileged access.

MitigationUpdate Flynax Bridge plugin to version 2.2.1 or later which should contain proper user identity validation. Until patched, consider disabling the plugin or implementing additional access controls at the web application firewall level.

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. Check the installed version of the Flynax Bridge plugin
    Log in to the WordPress admin dashboard and navigate to Plugins > Installed Plugins. Locate 'Flynax Bridge' in the list and check the version number displayed below the plugin name. Alternatively, inspect the plugin header in wp-content/plugins/flynax-bridge/flynax-bridge.php to read the 'Version' comment field.
    Affected if The installed version is 2.2.0 or lower.
  2. Verify the Flynax Bridge plugin is active
    In the WordPress admin under Plugins > Installed Plugins, confirm that the 'Flynax Bridge' plugin shows as 'Active'. If it is deactivated or uninstalled, the vulnerability cannot be exploited.
    Affected if The plugin is installed and active.
  3. Inspect access to the plugin's password reset endpoint
    Check if the WordPress site exposes the Flynax Bridge password reset functionality. Common access paths include direct access to plugin PHP files handling password operations, typically found in the flynax-bridge plugin directory. Examine server access logs for POST requests to plugin endpoints containing keywords like 'reset', 'password', or 'bridge'.
    Affected if The password reset/update endpoints of the plugin are accessible without authentication.

You are affected if the Flynax Bridge plugin version is 2.2.0 or lower and the plugin is active and its password reset endpoints are accessible.
