Vulnerability Overview
The Motors - Car Dealer, Rental & Listing WordPress theme theme for WordPress is vulnerable to unauthorized arbitrary plugin installation due to a missing capability check on the 'mvl_theme_install_base' function in all versions up to, and including, 5.6.82. This makes it possible for authenticated attackers, with Subscriber-level access and above, to upload arbitrary plugins from arbitrary locations which makes remote code execution possible.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.
CWE-862: Missing Authorization
Motors - Car Dealer, Rental & Listing WordPress theme <= 5.6.82 carries this weakness at mvl_theme_install_base, and reaching it takes an account at Subscriber level or above. A missing authorization check means a function is reachable by anyone who can reach the endpoint, because the code never asks whether the caller is allowed to perform the action.
Any user who can reach the endpoint gets to run an action reserved for higher-privileged roles, from reading protected data to changing settings or content. For Motors - Car Dealer, Rental & Listing WordPress theme the fix is 5.6.83: builds <= 5.6.82 are affected, anything from 5.6.83 onward is not.
Remediation
Update to version 5.6.83, or a newer patched version
How does WordSec protect against this?
Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: Motors - Car Dealer, Rental & Listing WordPress theme 5.6.83 closes this, and updating the theme is the step that ends it.
