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
Subscriber Broken Access Control in Advanced Form Integration <= 1.126.12 versions.

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 confidence

This is a Broken Access Control vulnerability in the Advanced Form Integration WordPress plugin (versions <= 1.126.12). Users with the Subscriber role (typically the lowest privilege role) can access administrative or privileged functionality they should not have access to, allowing potential unauthorized actions within the plugin or WordPress environment.

MitigationUpdate to a version newer than 1.126.12 if available, or implement proper capability checks (current_user_can) and nonce verification on all plugin functions that should be restricted to higher-privileged roles.

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. Confirm plugin installation and activation status
    Navigate to WordPress admin dashboard > Plugins > Installed Plugins. Look for 'Advanced Form Integration' in the list and verify the plugin is active.
    Affected if The plugin is installed and active in WordPress
  2. Identify installed plugin version
    In the plugins list, locate 'Advanced Form Integration' and note the version number displayed below the plugin name. Alternatively, check the plugin's main PHP file header for the 'Version' tag.
    Affected if The installed version is 1.126.12 or any earlier version
  3. Verify presence of Subscriber role users
    Go to Users > All Users in WordPress admin. Review the list of users and check the 'Role' column to identify any users assigned the Subscriber role.
    Affected if There is at least one user with the Subscriber role active on the site
  4. Test access control for privileged plugin functions
    Using a Subscriber-level account, attempt to access plugin administrative pages or functions (e.g., plugin settings, form integration pages, or any admin AJAX actions triggered by the plugin). Observe whether the requests are allowed or blocked.
    Affected if Subscriber users can access plugin pages or functions that should be restricted to administrators or higher-privileged roles

Your environment is affected if the Advanced Form Integration plugin version is 1.126.12 or earlier AND the plugin is active AND at least one Subscriber role user exists who can access administrative functionality they should not reach.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Update to a version newer than 1.126.12 if available, or implement proper capability checks (current_user_can) and nonce verification on all plugin functions that should be restricted to higher-privileged roles.

Recommended fix Moderate confidence

Any version of Advanced Form Integration higher than 1.126.12 (check WordPress plugin repository for the latest stable release)

  1. 1. Log in to the WordPress admin dashboard
  2. 2. Navigate to Plugins > Installed Plugins
  3. 3. Locate 'Advanced Form Integration' plugin
  4. 4. If an update is available, click 'Update Now' to upgrade to the latest version (version higher than 1.126.12)
  5. 5. After updating, verify the plugin version in the plugins list to confirm the upgrade was successful
  6. 6. Test the form integration functionality to ensure the update did not break existing features
  7. 7. Test with a subscriber-level user account to verify the broken access control has been remediated
