CVE-2026-104749
Bit integrations <= 2.10.6 - Unauthenticated Privilege Escalation via Identity-Confused Log Re-execution to Account Takeover via Log Re-execution of Anonymous-Captured Field Data
Description

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 administrator's 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 administrator's 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 plugin's log screen.
