The WPFront Notification Bar plugin for WordPress is vulnerable to Reflected Cross-Site Scripting in versions up to, and including, 3.5.1. This is due to the debug-log output path (writedebuglogs) reflecting the raw value of $SERVER['REQUESTURI'] through vprintf() directly inside a <script> block emitted on wpfooter, without any sanitization or escaping (see the 'Current URL is "%s"' log entry produced by the URL-text display filter in the filter() method). This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a specially crafted link.

The WPFront User Role Editor plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 4.2.1. This is due to missing or incorrect nonce validation on the whitelistoptions() function. This makes it possible for unauthenticated attackers to update the default role option that can be leveraged for privilege escalation via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. This is only exploitable on multisite instances.

The WPFront User Role Editor plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 3.2.1.11184 via the wpfrontuserroleeditorassignrolesuserautocomplete AJAX action. This makes it possible for authenticated attackers, with subscriber-level access and above, to extract retrieve a list of all user email addresses who are registered on the site.

The WPFront Notification Bar plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘wpfront-notification-bar-options[customclass]’ parameter in all versions up to, and including, 3.3.2 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. This only affects multi-site installations and installations where unfilteredhtml has been disabled.

The WPFront User Role Editor WordPress plugin before 3.2.1.11184 does not sanitise and escape the changes-saved parameter before outputting it back in the admin dashboard, leading to a Reflected Cross-Site Scripting

The WPFront Notification Bar WordPress plugin before 2.1.0.08087 does not properly sanitise and escape its settings, which could allow high privilege users to perform Cross-Site Scripting attacks even when the unfilteredhtml capability is disallowed.

The WPFront Scroll Top WordPress plugin before 2.0.6.07225 does not sanitise or escape its Image ALT setting before outputting it attributes, leading to an Authenticated Stored Cross-Site Scripting issues even when the unfilteredhtml capability is disallowed.

The WPFront Notification Bar WordPress plugin before 2.0.0.07176 does not sanitise or escape its Custom CSS setting, allowing high privilege users such as admin to set XSS payload in it even when the unfilteredhtml capability is disallowed, leading to an authenticated Stored Cross-Site Scripting issue
