TL;DR

Filament admin list queries in the package lacked proper authorization scoping, allowing users to view records belonging to other tenants (such as leaked titles, slugs, or statuses). User-owned models were insufficiently filtered by user_id, resulting in potential cross-tenant data exposure.

You are affected if you are using a version that falls within the vulnerable range.
