This broken access control vulnerability in the WordPress plugin permits unauthorized users to perform privileged actions without proper authentication or authorization checks.

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 MemberPress plugin is installed
    Check the WordPress plugins directory at wp-content/plugins/ for the memberpress folder, or run 'wp plugin list --status=active --format=json' to list active plugins
    Affected if MemberPress plugin is present and active in the WordPress installation
  2. Identify installed MemberPress version
    Open the main plugin file (typically memberpress.php) in the memberpress plugin folder and locate the 'Version' header in the plugin comments, or check in WordPress admin under Plugins > Installed Plugins
    Affected if The version displayed is less than 1.11.35
  3. Compare version against vulnerability threshold
    Review the version number found in the previous step against the affected range: any version below 1.11.35 is vulnerable
    Affected if The installed version is any version lower than 1.11.35, as the missing authorization check exists in the plugin code itself and requires no specific configuration to be exploitable

A user is affected if the installed MemberPress version is below 1.11.35, as the broken access control vulnerability exists in the plugin code itself regardless of configuration settings.
