Missing Authorization vulnerability in WPMU DEV - Your All-in-One WordPress Platform Defender Security defender-security.This issue affects Defender Security: from n/a through <= 4.7.1.

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 wpmudevappointments cookie. This allows unauthenticated attackers to inject a PHP Object. Attackers were actively exploiting this vulnerability with the WPTheme() class to create backdoors.

The WPMU DEV Dashboard plugin for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 5.0.1. This is due to inconsistent and ambiguous HMAC message construction between the unauthenticated wdpssostep1 and wdpssostep2 AJAX actions, where step 1 signs and discloses an unseparated concatenation of the token, state, redirect, and domain values, while step 2 verifies an unseparated concatenation that omits the domain field. This makes it possible for unauthenticated attackers, on sites connected to WPMU DEV with Hub SSO enabled and mapped to an administrator, to obtain a valid HMAC from step 1 and replay it to step 2 by moving the domain value into the redirect field, resulting in an authenticated administrator session.

The Forminator Forms – Contact Form, Payment Form & Custom Form Builder plugin for WordPress is vulnerable to unauthorized access due to a missing capability check on a function in all versions up to, and including, 1.35.1. This makes it possible for authenticated attackers, with Contributor-level access and above, and permissions granted by an Administrator, to create new or edit existing forms, including updating the default registration role to Administrator on User Registration forms.

Missing Authorization vulnerability in WPMU DEV - Your All-in-One WordPress Platform Hummingbird hummingbird-performance.This issue affects Hummingbird: from n/a through <= 3.9.1.

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 'entrydeleteuploadfiles' 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.

The WPMU DEV Dashboard plugin for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 5.0.0. On sites not yet connected to the WPMU DEV Hub — the default state after installation — the site API key that keys the WDP-AUTH request signature is empty, making the signature verified by validatehash() trivially forgeable; version 5.0.0 additionally removed the replay check in validatenonce(), and the remote handler is bound to the public init hook with no capability check. This makes it possible for unauthenticated attackers to invoke privileged Hub actions — including installing and activating a plugin from an attacker-supplied URL (resulting in remote code execution), deleting plugins and themes, upgrading WordPress core, or logging in as an administrator via SSO. Sites connected to a WPMU DEV account, which have a non-empty 64-character API key, are not affected.

Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in WPMU DEV - Your All-in-One WordPress Platform Broken Link Checker broken-link-checker allows Blind SQL Injection.This issue affects Broken Link Checker: from n/a through <= 2.4.7.

The Forminator – Contact Form, Payment Form & Custom Form Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘id’ forminatorform shortcode attribute in versions up to, and including, 1.29.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The Forminator Forms – Contact Form, Payment Form & Custom Form Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the slider template data in all versions up to, and including, 1.39.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The Forminator Forms – Contact Form, Payment Form & Custom Form Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘limit’ parameter in all versions up to, and including, 1.42.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

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. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in WPMU DEV Broken Link Checker allows Stored XSS.This issue affects Broken Link Checker: from n/a through 2.2.3.

Missing Authorization vulnerability in WPMU DEV - Your All-in-One WordPress Platform SmartCrawl smartcrawl-seo.This issue affects SmartCrawl: from n/a through <= 3.14.3.

The SmartCrawl WordPress SEO checker, SEO analyzer, SEO optimizer plugin for WordPress is vulnerable to unauthorized ld+json description injection due to a missing capability check on the savesettings function in all versions up to, and including, 3.10.2. This makes it possible for unauthenticated attackers to save schema types.

Exposure of Sensitive System Information to an Unauthorized Control Sphere vulnerability in WPMU DEV - Your All-in-One WordPress Platform Hustle wordpress-popup allows Retrieve Embedded Sensitive Data.This issue affects Hustle: from n/a through <= 7.8.9.2.

Missing Authorization vulnerability in WPMU DEV - Your All-in-One WordPress Platform Forminator forminator allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects Forminator: from n/a through <= 1.50.2.

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 'hustlemoduleconverted' 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.

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.

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 ForminatorAdminModuleEditPage (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 manageforminatormodules capability. The nonce used (forminatorformrequest) 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 adminmenu 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.

Missing Authorization vulnerability in WPMU DEV Hustle allows Exploiting Incorrectly Configured Access Control Security Levels.

This issue affects Hustle: through 7.8.10.1.

The Smush plugin for WordPress is vulnerable to unauthorized deletion of the resmush list due to a missing capability check on the deleteresmushlist() function. This makes it possible for authenticated attackers, with minimal permissions such as a subscriber, to delete the resmush list for Nextgen or the Media Library.

The Forminator Forms – Contact Form, Payment Form & Custom Form Builder plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.35.1. This is due to missing or incorrect nonce validation on the custom form 'createmodule' function. This makes it possible for unauthenticated attackers to create draft forms via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
