What the vulnerability does
The Clasifico Listing plugin for WordPress is vulnerable to privilege escalation in versions up to, and including, 2.0. This is due to the plugin allowing users who are registering new accounts to set their own role by supplying the 'listing_user_role' parameter. This makes it possible for unauthenticated attackers to gain elevated privileges by registering an account with the administrator role.
Explanation of Vulnerability in Simple Terms
Clasifico Listing versions 2.0 and earlier contain a privilege management flaw that allows unauthenticated attackers to gain full control over the application. An attacker can read sensitive data, modify content, and disrupt service without needing valid credentials or user interaction. All installations should update immediately.
What an attacker can do
Read sensitive data, modify content, and disrupt service without authentication.
