CVE-2026-48810 Details
Description
FreeScout is a free help desk and shared inbox built with PHP's Laravel framework. Prior to 1.8.221, while investigating the ThreadPolicy::delete issue reported previously, the same missing mailbox membership check was found in the sibling ThreadPolicy::edit method. A user with the PERM_EDIT_CONVERSATIONS permission who created a message or internal note in Mailbox A can rewrite that thread's body after an administrator removes them from Mailbox A, because the policy checks only authorship and a global permission flag — not current mailbox membership. This vulnerability is fixed in 1.8.221.
A vulnerability in FreeScout prior to version 1.8.221 allows users with the PERM_EDIT_CONVERSATIONS permission to bypass mailbox membership checks when editing conversation threads. This issue arises because the authorization process only considers authorship and a global permission flag, neglecting current mailbox access. As a result, an agent who has been removed from a mailbox can still modify thread content in conversations they can no longer access.
Users are advised to update FreeScout to version 1.8.221 or later, where this vulnerability has been fixed.
