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 Webinar Solution: Create live/evergreen/automated/instant webinars, stream & Zoom Meetings | WebinarIgnition plugin for WordPress is vulnerable to unauthenticated login token generation due to a missing capability check on the `webinarignition_sign_in_support_staff` and `webinarignition_register_support` functions in all versions up to, and including, 4.03.32. This makes it possible for unauthenticated attackers to generate login tokens for arbitrary WordPress users under certain circumstances, issuing authorization cookies which can lead to authentication bypass.

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 WebinarIgnition WordPress plugin versions up to 4.03.32 lack capability checks on the `webinarignition_sign_in_support_staff` and `webinarignition_register_support` functions, allowing unauthenticated attackers to generate valid login tokens for arbitrary WordPress users. This broken access control enables full authentication bypass by issuing authorization cookies for any user account.

MitigationUpdate to version 4.03.33 or later which implements proper capability checks. If an update is unavailable, disable the plugin and review access logs for suspicious token generation activity.

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 WebinarIgnition plugin is installed
    Check for the presence of the webinarignition plugin directory in wp-content/plugins/ or query the WordPress database table wp_options for option_name = 'active_plugins' and look for webinarignition in the serialized array
    Affected if The plugin is not found in the active plugins list, then the vulnerability does not apply to this environment
  2. Determine the installed plugin version
    Open the main plugin file (webinarignition.php) and read the Version header from the plugin comment block, or query the WordPress database: SELECT option_value FROM wp_options WHERE option_name = 'webinarignition_version'
    Affected if The installed version is 4.03.32 or lower, placing it within the affected range
  3. Check if the vulnerable functions exist in the codebase
    Search the plugin files for the function names 'webinarignition_sign_in_support_staff' and 'webinarignition_register_support' using grep or a file search in the plugin directory
    Affected if These functions are present in the code, indicating the vulnerable code path exists regardless of version number
  4. Verify if the vulnerable functions are hooked to accessible endpoints
    Search for add_action or add_filter calls that register these functions to AJAX hooks (wp_ajax_) or REST API routes, looking specifically for hooks without 'nopriv' or capability checks
    Affected if The functions are hooked to AJAX or REST endpoints accessible to unauthenticated users (hooks like wp_ajax_webinarignition_sign_in_support_staff without corresponding wp_ajax_nopriv_ handlers)

The environment is affected if WebinarIgnition plugin version 4.03.32 or lower is installed AND the vulnerable sign_in_support_staff/register_support functions are hooked to publicly accessible AJAX or REST endpoints without capability verification.

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

Update to version 4.03.33 or later which implements proper capability checks. If an update is unavailable, disable the plugin and review access logs for suspicious token generation activity.
