The Bit integrations – Form Integration, Webhook, Spreadsheets, CRM, LMS & Email Automation plugin for WordPress is vulnerable to Privilege Escalation via Log Re-execution in all versions up to, and including, 2.10.6 The vulnerability exists because IntegrationHandler::executeWithCapture() stores raw, attacker-controlled field values — including user_pass and user_email — verbatim into wp_btcbi_log.field_data on anonymous front-end requests with no capability check, and LogHandler::reexecute() feeds that stored payload back through Flow::execute() inside the replaying administrators session without validating the identity that originally produced the data, causing RegistrationController::updateUser() to resolve the target user ID to the administrator and write the attacker-supplied password via wp_update_user(). This makes it possible for unauthenticated attackers to overwrite the administrators password and fully take over the administrator account. Exploitation requires that an administrator has configured a flow mapping a user-supplied form field to the user_pass parameter of the WP User Registration Update User action, and that the administrator subsequently clicks Re-execute on the failure log row produced by the anonymous submission from the plugins log screen.
Weakness
The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
