The PhpList Subber plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.1. This is due to missing or incorrect nonce validation on the bulkactionhandler function. This makes it possible for unauthenticated attackers to trigger bulk synchronization of subscription forms via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

phpList before 3.6.15 is vulnerable to Reflected Cross-Site Scripting (XSS) via the /lists/dl.php endpoint. An attacker can inject arbitrary JavaScript code by manipulating the id parameter, which is improperly sanitized.

phpList before 3.6.15 is vulnerable to Cross-Site Scripting (XSS) due to improper input sanitization in lt.php. The vulnerability is exploitable when the application dynamically references internal paths and processes untrusted input without escaping, allowing an attacker to inject malicious JavaScript.

An issue was discovered in phpList 3.6.12. Due to an access error, it was possible to manipulate and edit data of the system's super admin, allowing one to perform an account takeover of the user with super-admin permission. Specifically, for a request with updatepassword=1, a modified request (manipulating both the ID parameter and the associated username) can bypass the intended email confirmation requirement. For example, the attacker can start from an updatepassword=1 request with their own ID number, and change the ID number to 1 (representing the super admin account) and change the username to admin2. In the first step, the attacker changes the super admin's email address to one under the attacker's control. In the second step, the attacker performs a password reset for the super admin account. The new password allows login as the super admin, i.e., a successful account takeover.
