dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify if Paid Memberships Pro CCBill Gateway plugin is installedCheck your WordPress plugin directory or plugin list for 'Paid Memberships Pro CCBill Gateway' or 'pmpro-csbill-gateway'Affected if The plugin appears in your installed plugins list

-
Check for sensitive membership or payment functions exposureReview the CCBill Gateway plugin files (PHP files in the plugin directory) for functions handling membership levels, payment processing, or user data that lack current_user_can() checks or nonce verification before executionAffected if Code review reveals membership or payment functions without proper authorization checks
-
Confirm WordPress user role requirements are enforcedTest by attempting to access CCBill-related URLs or actions while logged out or as a subscriber-level user, or examine the code for add_action/do_action calls lacking capability checks like 'manage_options'Affected if Sensitive CCBill operations execute without verifying user roles or capabilities
