Technical details
The plugin implements an Insecure Direct Object Reference (IDOR) vulnerability in its listing retrieval logic. The flaw lies in the absence of authorization checks before returning non-published listings; an unauthenticated attacker can enumerate user IDs and access draft, pending, and private car listings by supplying only the numeric user ID as a request parameter. No authentication, special roles, or user interaction is required—only network access to the affected WordPress site. An attacker can retrieve sensitive data including listing titles, prices, media URLs, and seller notes. The vulnerability was fixed in version 1.4.121.
