CVE-2026-11794: WordPress AFI Auth Bypass Vulnerability

CVE-2026-11794 Overview

CVE-2026-11794 affects the Advanced Form Integration — Connect Forms to 200+ Apps WordPress plugin in versions before 2.1.1. The plugin fails to restrict the WordPress role assigned when creating a user from a public form submission. Unauthenticated visitors can create an administrator account when an active integration maps the user role to a public form field. Exploitation requires a specific, non-default plugin configuration where the role field is exposed on a public form.

Critical Impact
Unauthenticated attackers can register administrator-level accounts on affected WordPress sites, resulting in full site takeover when the vulnerable role-mapping configuration is in place.

Affected Products

Advanced Form Integration — Connect Forms to 200+ Apps WordPress plugin versions prior to 2.1.1
WordPress installations using this plugin with public form-to-user integrations enabled
Sites where the WordPress user role is mapped to a public form field

Technical Details for CVE-2026-11794

Vulnerability Analysis

The vulnerability is a broken access control flaw leading to privilege escalation. The Advanced Form Integration plugin supports creating WordPress users as part of its integration workflow. When a public form submission triggers user creation, the plugin accepts the target role from form-submitted data without server-side validation or allow-listing of role values.

An attacker submits a crafted form request that sets the role parameter to administrator. The plugin then provisions a WordPress account with administrator privileges. Because form submissions do not require authentication, any anonymous visitor can trigger the flow when the site configuration exposes the role field.

The attack complexity is elevated because the exploit depends on a non-default configuration. The site owner must have configured an active integration that maps a public form field to the WordPress user role. Where this configuration exists, exploitation is straightforward and yields full site compromise.

Root Cause

The root cause is missing authorization and missing input validation on the role assignment logic. The plugin trusts client-supplied data for a security-critical field. There is no check that verifies the submitter is authorized to assign elevated roles, and no restriction that prevents privileged role values from being accepted on public forms.

Attack Vector

The attack vector is network-based and requires no authentication or user interaction. An attacker identifies a public form on a target WordPress site that uses the Advanced Form Integration plugin with a role-mapping integration. The attacker submits the form with the role field set to administrator. The plugin creates the account, and the attacker logs in with full administrative control.

See the WPScan Vulnerability Report for further technical details.

Detection Methods for CVE-2026-11794

Indicators of Compromise

Unexpected WordPress user accounts with the administrator role created shortly after public form submissions
New administrator accounts registered from IP addresses associated with anonymous form traffic
Entries in the WordPress users and usermeta tables that lack a corresponding admin-initiated creation event in audit logs
Successful logins from newly created accounts followed by plugin, theme, or user modifications

Detection Strategies

Audit installed versions of the Advanced Form Integration plugin and flag any instance below 2.1.1
Review plugin integration configurations for form-to-user mappings that expose a role field on a public form
Correlate WordPress user creation events with HTTP POST requests to form submission endpoints
Query the WordPress database for accounts with the wp_capabilities meta value containing administrator and compare against approved admin lists

Monitoring Recommendations

Enable WordPress audit logging for user creation, role assignment, and capability changes
Alert on any administrator role assignment that does not originate from an authenticated admin session
Monitor web server access logs for repeated POST requests to form endpoints containing role-related parameters
Track plugin configuration changes to detect newly enabled role-mapping integrations

How to Mitigate CVE-2026-11794

Immediate Actions Required

Update the Advanced Form Integration plugin to version 2.1.1 or later on all WordPress sites
Review all active integrations and remove any mapping that ties the WordPress user role to a public form field
Audit the WordPress users table and remove unrecognized administrator accounts
Rotate credentials and force a password reset for all remaining administrator accounts if unauthorized accounts were found

Patch Information

The vendor has released version 2.1.1 of the Advanced Form Integration — Connect Forms to 200+ Apps plugin, which restricts the role that can be assigned through public form submissions. Site administrators should update through the WordPress plugin manager or by downloading the patched release. Refer to the WPScan Vulnerability Report for advisory details.

Workarounds

Disable the Advanced Form Integration plugin until the update to 2.1.1 can be applied
Reconfigure integrations so the user role is set to a fixed low-privilege value such as subscriber rather than sourced from a form field
Remove role fields from all public-facing forms handled by the plugin
Restrict access to form submission endpoints behind authentication or a web application firewall rule until patching is complete

bash

# Configuration example: verify plugin version via WP-CLI and update
wp plugin get advanced-form-integration --field=version
wp plugin update advanced-form-integration --version=2.1.1

# Identify administrator accounts for review
wp user list --role=administrator --fields=ID,user_login,user_email,user_registered
