Recent Wpmudev Security Vulnerabilities

CVE	Date	Vulnerability	Products
CVE-2026-11551	Jun 19, 2026	Branda WP Plugin <3.4.29: Privilege Escalation via Password Change The Branda plugin for WordPress is vulnerable to privilege escalation via account takeover in all versions up to, and including, 3.4.29. This is due to the plugin not properly validating a user's identity prior to updating their password. This makes it possible for unauthenticated attackers to change arbitrary user's passwords, including administrators, and leverage that to gain access to their account.	Branda
CVE-2026-6214	May 07, 2026	WordPress Forminator <1.53.0 Missing Auth Leads to Export Exfiltration The Forminator Forms plugin for WordPress is vulnerable to Missing Authorization in versions up to and including 1.53.0. This is due to the listen_for_saving_export_schedule() function in library/class-export.php failing to perform a capability check before saving the scheduled export configuration, unlike the parallel listen_for_csv_export() function which correctly verifies user permissions. This makes it possible for authenticated attackers with subscriber-level access to configure a scheduled export job that emails all form submissions to an attacker-controlled email address, resulting in sensitive data exfiltration.	Forminator Forms
CVE-2026-6222	May 07, 2026	WordPress Forminator <1.51.1 Missing Auth Export/Clone The Forminator Forms plugin for WordPress is vulnerable to Missing Authorization in versions up to and including 1.51.1. This is due to the `processRequest()` method in `Forminator_Admin_Module_Edit_Page` (admin/abstracts/class-admin-module-edit-page.php) dispatching sensitive module-management actions including export, delete, clone, delete-entries, publish/draft, and bulk variants after only a nonce check, without ever verifying that the current user holds the `manage_forminator_modules` capability. The nonce used (`forminator_form_request`) is unconditionally embedded in the global `forminatorData` JavaScript object and localized on every Forminator admin page, including Templates and Reports pages accessible to users who explicitly lack module-management permissions. Because `processRequest()` is invoked during the `admin_menu` action hook which fires before WordPress enforces page-level capability checks a user whose Forminator role is restricted to Templates or Reports can craft a valid POST request targeting any published module and successfully trigger the vulnerable actions. This makes it possible for authenticated attackers with subscriber-level access (or any custom low-privilege Forminator role) to export the complete internal configuration of arbitrary forms/polls/quizzes (including notification routing, integration credentials, and conditional logic), delete modules, delete all submissions/votes, clone modules, or bulk-change publish/draft status.	Forminator Forms
CVE-2026-5192	May 05, 2026	Forminator WP Plugin 1.52.1 Path Traversal via upload-1[file][file_path] The Forminator Forms Contact Form, Payment Form & Custom Form Builder plugin for WordPress is vulnerable to Path Traversal in versions up to, and including, 1.52.1 via the 'upload-1[file][file_path]' parameter. This makes it possible for unauthenticated attackers to read the contents of arbitrary files on the server, which can contain sensitive information. Successful exploitation requires a publicly accessible form with a File Upload field where Save and Continue is enabled in that form's Behavior settings and the Save and Continue email notification is configured to attach uploaded files in Email Notifications.	Forminator Forms
CVE-2026-2729	May 05, 2026	Forminator WP Plugin <=1.52.0 Auth Bypass via Stripe PaymentIntent The Forminator plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.52.0. This is due to the plugin not properly verifying that a user is authorized to perform an action when processing attacker-supplied Stripe PaymentIntent identifiers in the public payment flow. This makes it possible for unauthenticated attackers to submit high-value paid forms as completed by reusing a previously succeeded low-value Stripe PaymentIntent, resulting in underpayment/payment bypass conditions.	Forminator Forms
CVE-2026-2263	Apr 07, 2026	The Hustle WP Plugin 7.x: Auth-Breach via hustle_module_converted AJAX The Hustle Email Marketing, Lead Generation, Optins, Popups plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'hustle_module_converted' AJAX action in all versions up to, and including, 7.8.10.2. This makes it possible for unauthenticated attackers to forge conversion tracking events for any Hustle module, including draft modules that are never displayed to users, thereby manipulating marketing analytics and conversion statistics.	Hustle
CVE-2026-2002	Feb 17, 2026	Forminator 1.50.2 XSS via form_name (admin) The Forminator Forms Contact Form, Payment Form & Custom Form Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the form_name parameter in all versions up to, and including, 1.50.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level access, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The plugin allows admins to give form management permissions to lower level users, which could make this exploitable by users such as subscribers.	Forminator Forms
CVE-2026-0911	Jan 24, 2026	Hustle WP plugin ARFU v7.8.9.2 (7.8.9.2) The Hustle Email Marketing, Lead Generation, Optins, Popups plugin for WordPress is vulnerable to arbitrary file uploads due to incorrect file type validation in the action_import_module() function in all versions up to, and including, 7.8.9.2. This makes it possible for authenticated attackers, with a lower-privileged role (e.g., Subscriber-level access and above), to upload arbitrary files on the affected site's server which may make remote code execution possible. Successful exploitation requires an admin to grant Hustle module permissions (or module edit access) to the low-privileged user so they can access the Hustle admin page and obtain the required nonce.	Hustle
CVE-2025-14782	Jan 09, 2026	Authorization Bypass in Forminator Forms <=1.49.1 via listen_for_csv_export The Forminator Forms Contact Form, Payment Form & Custom Form Builder plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.49.1 via the 'listen_for_csv_export' function. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with access to the Forminator dashboard, to export sensitive form submission data including personally identifiable information.	Forminator Forms
CVE-2025-14998	Jan 02, 2026	Branda WP Plugin <=3.4.24 Privilege Escalation via Password Reset The Branda plugin for WordPress is vulnerable to privilege escalation via account takeover in all versions up to, and including, 3.4.24. This is due to the plugin not properly validating a user's identity prior to updating their password. This makes it possible for unauthenticated attackers to change arbitrary user's passwords, including administrators, and leverage that to gain access to their account.	Branda
CVE-2025-14437	Dec 18, 2025	Hummingbird Perf <=3.18.0 Sensitive Info Exposure via request() The Hummingbird Performance plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 3.18.0 via the 'request' function. This makes it possible for unauthenticated attackers to extract sensitive data including Cloudflare API credentials.
CVE-2017-20206	Oct 18, 2025	Appointments 2.2.1 PHP Object Injection via wpmudev_appointments cookie The Appointments plugin for WordPress is vulnerable to PHP Object Injection in versions up to, and including, 2.2.1 via deserialization of untrusted input from the `wpmudev_appointments` cookie. This allows unauthenticated attackers to inject a PHP Object. Attackers were actively exploiting this vulnerability with the WP_Theme() class to create backdoors.
CVE-2025-11163	Sep 30, 2025	SmartCrawl WP Plugin 3.14.3 Auth Data Mod via missing capability check The SmartCrawl SEO checker, analyzer & optimizer plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the update_submodule() function in all versions up to, and including, 3.14.3. This makes it possible for authenticated attackers, with Subscriber-level access and above, to update the plugin's setttings.
CVE-2025-7638	Jul 18, 2025	Forminator Forms <1.45.0 Vulnerable to Time-Based SQLI via order_by The Forminator Forms Contact Form, Payment Form & Custom Form Builder plugin for WordPress is vulnerable to time-based SQL Injection via the `order_by` parameter in all versions up to, and including, 1.45.0 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with Administrator-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.	Forminator Forms
CVE-2025-6464	Jul 02, 2025	PHP Object Injection via entry_delete_upload_files in Forminator Forms <=1.44.2 The Forminator Forms Contact Form, Payment Form & Custom Form Builder plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 1.44.2 via deserialization of untrusted input in the 'entry_delete_upload_files' function. This makes it possible for unauthenticated attackers to inject a PHP Object through a PHAR file. No known POP chain is present in the vulnerable software, which means this vulnerability has no impact unless another plugin or theme containing a POP chain is installed on the site. If a POP chain is present via an additional plugin or theme installed on the target system, it may allow the attacker to perform actions like delete arbitrary files, retrieve sensitive data, or execute code depending on the POP chain present. Deserialization occurs when the form submission is deleted, whether by an Administrator or via auto-deletion determined by plugin settings.	Forminator Forms
CVE-2025-6463	Jul 02, 2025	Forminator <1.44.2 Inf File Delete via entry_delete_upload_files The Forminator Forms Contact Form, Payment Form & Custom Form Builder plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the 'entry_delete_upload_files' function in all versions up to, and including, 1.44.2. This makes it possible for unauthenticated attackers to include arbitrary file paths in a form submission. The file will be deleted when the form submission is deleted, whether by an Administrator or via auto-deletion determined by plugin settings. This can easily lead to remote code execution when the right file is deleted (such as wp-config.php).	Forminator Forms
CVE-2025-5341	Jun 05, 2025	Stored XSS via id & data-size in Forminator <=1.44.1 (Contributor+) The Forminator Forms Contact Form, Payment Form & Custom Form Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the id' and 'data-size parameters in all versions up to, and including, 1.44.1 due to insufficient input sanitization and output escaping.
