What is CVE-2026-48811?

FreeScout, a free help desk application built on PHP's Laravel framework, has an authorization flaw that enables non-admin users to permanently delete internal notes from any conversation. This weakness occurs even after the user’s access to the corresponding mailbox has been revoked. The insufficient validation in the ThreadPolicy::delete authorization policy fails to check for mailbox membership, allowing former team members to retain destructive capabilities over notes they previously created. This vulnerability was addressed in version 1.8.221.
