CVE-2026-32395: Xpro Beaver Builder Auth Bypass Flaw

CVE-2026-32395 Overview

CVE-2026-32395 is a Missing Authorization vulnerability affecting the Xpro Addons For Beaver Builder – Lite WordPress plugin. This broken access control flaw allows attackers to exploit incorrectly configured access control security levels, potentially enabling unauthorized actions on WordPress sites running vulnerable versions of the plugin.

The vulnerability stems from missing authorization checks (CWE-862) in the xpro-addons-beaver-builder-elementor plugin, which fails to properly verify user permissions before allowing certain operations. This can be exploited remotely over the network without authentication, allowing attackers to modify data or settings they should not have access to.

Critical Impact
Unauthenticated attackers can bypass access controls to perform unauthorized actions on WordPress sites, potentially compromising site integrity.

Affected Products

Xpro Addons For Beaver Builder – Lite versions through 1.5.6
WordPress installations using the xpro-addons-beaver-builder-elementor plugin

Technical Details for CVE-2026-32395

Vulnerability Analysis

This vulnerability is classified as a Missing Authorization flaw (CWE-862), which occurs when the plugin fails to implement proper access control checks before executing privileged operations. The attack can be performed remotely over the network with low complexity and requires no user interaction or prior authentication.

The impact is focused on integrity rather than confidentiality or availability. An attacker exploiting this vulnerability can make unauthorized modifications to the WordPress site, but cannot directly access sensitive data or cause service disruption through this specific flaw.

Root Cause

The root cause is the absence of proper authorization verification in the Xpro Addons For Beaver Builder – Lite plugin. When users or external actors make requests to certain plugin functionality, the code fails to validate whether the requesting party has appropriate permissions to perform the requested action. This is a common issue in WordPress plugins where developers implement features without properly integrating WordPress's capability and role checking mechanisms.

Specifically, the plugin does not properly leverage WordPress authentication functions such as current_user_can() or nonce verification to protect sensitive operations, leaving them accessible to unauthenticated users.

Attack Vector

The vulnerability is exploited via the network (AV:N) with low attack complexity (AC:L). An attacker can directly send crafted HTTP requests to the vulnerable WordPress installation without requiring any authentication (PR:N) or user interaction (UI:N).

The attack flow typically involves:

Identifying a WordPress site running the vulnerable Xpro Addons For Beaver Builder – Lite plugin version 1.5.6 or earlier
Crafting HTTP requests to plugin endpoints that lack authorization checks
Submitting these requests to perform unauthorized modifications on the target site

The exploitation mechanism relies on identifying AJAX handlers or REST API endpoints registered by the plugin that do not properly verify user capabilities before processing requests. For technical details, refer to the Patchstack security advisory.

Detection Methods for CVE-2026-32395

Indicators of Compromise

Unusual HTTP requests to WordPress AJAX endpoints associated with the Xpro Addons plugin
Unexpected modifications to site content or settings without corresponding admin activity
Server logs showing unauthorized access attempts to plugin-specific endpoints
Changes to plugin configuration or widgets without legitimate admin authentication

Detection Strategies

Monitor WordPress access logs for requests to admin-ajax.php with actions related to xpro or beaver-builder that originate from unauthenticated sessions
Implement web application firewall (WAF) rules to detect and block suspicious requests targeting known vulnerable endpoints
Review WordPress audit logs for configuration or content changes made by unauthenticated or unexpected users
Deploy endpoint detection solutions to monitor for unauthorized file or database modifications

Monitoring Recommendations

Enable detailed logging on WordPress installations to capture all AJAX and REST API requests
Configure alerts for unusual patterns of requests to plugin-specific endpoints
Regularly audit WordPress plugin versions against known vulnerability databases
Implement file integrity monitoring to detect unauthorized changes to WordPress files and database entries

How to Mitigate CVE-2026-32395

Immediate Actions Required

Update Xpro Addons For Beaver Builder – Lite to a version newer than 1.5.6 as soon as a patch is available
Temporarily deactivate the Xpro Addons For Beaver Builder – Lite plugin if updates are not yet available
Implement WAF rules to restrict access to vulnerable plugin endpoints
Review WordPress audit logs for signs of exploitation

Patch Information

WordPress administrators should check for an updated version of the Xpro Addons For Beaver Builder – Lite plugin that addresses this missing authorization vulnerability.
