AI-suggested

A fix is available in Motors plugin version 1.4.121. Users should upgrade to version 1.4.121 or later to remediate this authorization bypass vulnerability. No other mitigation is indicated by the vendor advisory.

Description

The Motors WordPress plugin before 1.4.121 does not verify that a request is authorized to view a user's non-published listings before returning them, allowing unauthenticated attackers to read any author's draft, pending and private car listings - including titles, prices, media URLs and seller notes - by supplying only the target's numeric user id.
