At a glance

CVE-2026-104749 is a high-severity Improper Privilege Management vulnerability in the Bit integrations WordPress plugin, affecting versions <= 2.10.6. It carries a CVSS score of 7.5 (reachable over the network; high confidentiality, integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 2.10.7; sites on affected versions should update now. Disclosed October 2026, reported by crow.

Vulnerability Overview

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.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, and no privileges on the target site. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

CWE-269: Improper Privilege Management

Bit integrations <= 2.10.6 carries this weakness at Re-execute, and reaching it takes no account at all. Improper privilege management means the code lets an account end up with capabilities its role should not have.

It converts a low-privileged account into an administrative one, which makes every other restriction on the site irrelevant. For Bit integrations the fix is 2.10.7: builds <= 2.10.6 are affected, anything from 2.10.7 onward is not.

Remediation

Update to version 2.10.7, or a newer patched version

How does WordSec protect against this?

This one needs no account at all, which puts it outside what login hardening can reach; WordSec's login security narrows the account-level paths around it, and the firewall is what inspects the request itself. None of that substitutes for the fix: Bit integrations 2.10.7 closes this, and updating the plugin is the step that ends it.
