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

A blind SQL injection vulnerability exists in the imithemes Eventer plugin (versions prior to 3.11.4) where user-supplied input is not properly sanitized before being used in SQL queries. An unauthenticated attacker could exploit this to execute arbitrary SQL commands and potentially extract sensitive data from the database.

MitigationUpdate the Eventer plugin to version 3.11.4 or later. If immediate update is not possible, disable the plugin until the patch can be applied.

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. Locate the Eventer plugin installation
    Check the WordPress plugins directory (wp-content/plugins/eventer) or view the installed plugins list in the WordPress admin panel
    Affected if The Eventer plugin by imithemes is installed on the WordPress site
  2. Identify the installed version
    Open the main plugin file (eventer.php) and look for the 'Version:' header in the plugin comments, or check the plugins list in WordPress admin
    Affected if The version number is 3.9.6 or lower, or any version prior to 3.11.4
  3. Confirm the plugin is active
    Check the WordPress admin under Plugins > Installed Plugins to see if Eventer is activated
    Affected if The Eventer plugin is currently active on the site
  4. Identify accessible SQL query endpoints
    Review the site for frontend pages that use Eventer shortcodes (such as [eventer] or eventer-archive) which handle user-supplied parameters like event categories or dates
    Affected if Public-facing pages utilizing Eventer shortcodes with user parameters are accessible without authentication

If the Eventer plugin is installed, active, and running version 3.9.6 or lower (or any version prior to 3.11.4) with publicly accessible shortcode endpoints, the site is likely affected by this blind SQL injection vulnerability.
