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 Crypto plugin for WordPress is vulnerable to authentication bypass in versions up to, and including, 2.19. This is due to missing validation on the user being supplied in the 'crypto_connect_ajax_process::register' function. This makes it possible for unauthenticated attackers to log in as any existing user on the site, such as an administrator, if they have access to the username.

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 Crypto plugin for WordPress versions up to 2.19 contains an authentication bypass vulnerability in the 'crypto_connect_ajax_process::register' function due to missing validation on the user parameter. Unauthenticated attackers can supply any existing username (such as an administrator) and gain authenticated access to that account without requiring password authentication.

MitigationUpdate the Crypto plugin to version 2.20 or later. If an update is unavailable, consider disabling the plugin or implementing additional access controls such as IP-based restrictions on the affected endpoint until a patch is available.

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 installed plugin version
    Navigate to WordPress admin dashboard > Plugins > Installed Plugins. Locate the 'Odude Crypto Tool' or 'Crypto' plugin and note the version number displayed. Compare this version against the affected range (2.15 and below).
    Affected if The installed version is 2.15 or lower.
  2. Identify the vulnerable AJAX action
    In a WordPress setup, the vulnerable function is crypto_connect_ajax_process::register registered via the wp_ajax_nopriv_ hook (for unauthenticated access). Inspect plugin source code or check network requests for admin-ajax.php?action=crypto_connect_ajax_process calls.
    Affected if The AJAX action 'crypto_connect_ajax_process' is registered and accessible to unauthenticated users (wp_ajax_nopriv_).
  3. Verify user registration is enabled
    The vulnerability exploits the registration functionality. Check WordPress general settings: Settings > General > 'Membership: Anyone can register' must be enabled for the attack to work.
    Affected if WordPress user registration is enabled and the Crypto plugin's registration endpoint is exposed.
  4. Audit for suspicious user accounts
    Review WordPress user list (Users > All Users) for newly created accounts with administrative roles that were not intentionally created, or accounts with usernames matching known legitimate users.
    Affected if Unexpected administrative-level accounts exist or legitimate user accounts show unusual last_login timestamps from unknown IP addresses.

A user is affected if the Crypto plugin version is 2.15 or lower AND the vulnerable AJAX endpoint is publicly accessible AND user registration is enabled on the WordPress site.
