The OptinMonster WordPress plugin is vulnerable to sensitive information disclosure and unauthorized setting updates due to insufficient authorization validation via the logged_in_or_has_api_key function in the ~/OMAPI/RestApi.php file that can used to exploit inject malicious web scripts on sites with the plugin installed. This affects versions up to, and including, 2.6.4.

The Hashthemes Demo Importer Plugin <= 1.1.1 for WordPress contained several AJAX functions which relied on a nonce which was visible to all logged-in users for access control, allowing them to execute a function that truncated nearly all database tables and removed the contents of wp-content/uploads.

The Accept Donations with PayPal WordPress plugin before 1.3.1 offers a function to create donation buttons, which internally are posts. The process to create a new button is lacking a CSRF check. An attacker could use this to make an authenticated admin create a new button. Furthermore, one of the Button field is not escaped before being output in an attribute when editing a Button, leading to a Stored Cross-Site Scripting issue as well.

The Flat Preloader WordPress plugin before 1.5.4 does not enforce nonce checks when saving its settings, as well as does not sanitise and escape them, which could allow attackers to a make logged in admin change them with a Cross-Site Scripting payload (triggered either in the frontend or backend depending on the payload)

The Formidable Form Builder WordPress plugin before 4.09.05 allows to inject certain HTML Tags like <audio>,<video>,<img>,<a> and<button>.This could allow an unauthenticated, remote attacker to exploit a HTML-injection byinjecting a malicous link. The HTML-injection may trick authenticated users to follow the link. If the Link gets clicked, Javascript code can be executed. The vulnerability is due to insufficient sanitization of the "data-frmverify" tag for links in the web-based entry inspection page of affected systems. A successful exploitation incomibantion with CSRF could allow the attacker to perform arbitrary actions on an affected system with the privileges of the user. These actions include stealing the users account by changing their password or allowing attackers to submit their own code through an authenticated user resulting in Remote Code Execution. If an authenticated user who is able to edit Wordpress PHP Code in any kind, clicks the malicious link, PHP code can be edit...

The WP Debugging WordPress plugin before 2.11.0 has its update_settings() function hooked to admin_init and is missing any authorisation and CSRF checks, as a result, the settings can be updated by unauthenticated users.

The Cookie Bar WordPress plugin before 1.8.9 doesn't properly sanitise the Cookie Bar Message setting, which could allow high privilege users to perform Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed
