What the vulnerability does
The Listee theme for WordPress is vulnerable to privilege escalation in all versions up to, and including, 1.1.6. This is due to a broken validation check in the bundled listee-core plugin's user registration function that fails to properly sanitize the user_role parameter. This makes it possible for unauthenticated attackers to register as Administrator by manipulating the user_role parameter during registration.
Explanation of Vulnerability in Simple Terms
Listee versions up to 1.1.6 contain a privilege management flaw that allows unauthenticated attackers to gain full control over the application. The vulnerability requires no user interaction and can be exploited remotely over the network. An attacker can read sensitive data, modify content, and disrupt service availability.
