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 Build App Online plugin for WordPress is vulnerable to account takeover due to a weak password reset mechanism in all versions up to, and including, 1.0.22. This makes it possible for unauthenticated attackers to reset the password of arbitrary users by guessing an 4-digit numeric reset code.

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 Build App Online WordPress plugin (versions up to 1.0.22) contains a critical account takeover vulnerability in its password reset function. The password reset code uses only a 4-digit numeric format (10,000 possible combinations), which is trivially brute-forceable by unauthenticated attackers. An attacker can reset any user's password by iteratively guessing the 4-digit code, gaining full account access.

MitigationUpdate the plugin to version 1.0.23 or later which implements a secure cryptographically-random reset token. If no patch is available, disable the plugin immediately and implement web application firewall rules to rate-limit password reset endpoints.

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. Verify the Build App Online plugin is installed
    Log in to WordPress admin and navigate to Plugins > Installed Plugins. Look for 'Buildapp Build App Online' or 'Build App Online' in the list. Alternatively, check the wp-content/plugins/ directory for a folder named 'buildapp' or similar.
    Affected if The plugin appears in the installed plugins list
  2. Determine the installed plugin version
    In WordPress admin plugins list, click on the plugin name to view details, or check the main plugin PHP file (usually in wp-content/plugins/buildapp/) for the 'Version' header in the plugin comment block. Alternatively, use WP-CLI: wp plugin list --name='buildapp'
    Affected if The version listed is 1.0.21 or lower
  3. Confirm password reset functionality is accessible
    Navigate to the site's login page and locate the 'Lost Password' or password reset link. Confirm the endpoint is accessible without authentication. Typical paths include /wp-login.php?action=lostpassword or /my-account/lost-password/
    Affected if The password reset form loads and accepts input without requiring login
  4. Inspect the password reset code for weak token generation
    Examine the plugin's password reset handler file (typically in includes/ or classes/ subfolder within the plugin directory). Look for functions handling the reset code generation. Search for rand(), mt_rand(), or similar functions generating a 4-digit numeric value.
    Affected if The code generates a numeric code with only 4 digits (range 0000-9999)

The environment is affected if the Build App Online plugin version is 1.0.21 or lower and the password reset functionality is active on the site.

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 data
Upgrade available Upgrade to a release after 1.0.21
Interim mitigation

Update the plugin to version 1.0.23 or later which implements a secure cryptographically-random reset token. If no patch is available, disable the plugin immediately and implement web application firewall rules to rate-limit password reset endpoints.
