Description

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.

Mitigating Controls (NIST 800-53 r5)AI

AC-2 Account Management good match
prevent

Establishes processes for account creation, including role assignment during registration, preventing unauthenticated users from arbitrarily setting elevated privileges like administrator.

SI-10 Information Input Validation good match
prevent

Validates user-supplied inputs such as the 'listing_user_role' parameter to ensure only authorized roles are accepted during account registration.

AC-6 Least Privilege good match
prevent

Enforces least privilege by ensuring newly registered accounts are assigned only the minimal roles necessary, blocking self-escalation to administrator.

Security SummaryAI

CVE-2025-12882 is a privilege escalation vulnerability in the Clasifico Listing plugin for WordPress, affecting versions up to and including 2.0. The issue arises because the plugin allows users registering new accounts to arbitrarily set their own user role by supplying the 'listing_user_role' parameter during registration. Classified under CWE-269 (Improper Privilege Management), it carries a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), reflecting its critical severity due to high impacts on confidentiality, integrity, and availability.

Unauthenticated attackers can exploit this vulnerability over the network with low complexity and no user interaction required. By registering a new account and setting the 'listing_user_role' parameter to 'administrator', attackers gain elevated administrator privileges on the WordPress site, enabling full control such as installing malicious plugins, modifying content, accessing sensitive data, or executing arbitrary code.
