FreeScout has Customer Edit Cross-Mailbox Email Takeover

概要

FreeScout has Customer Edit Cross-Mailbox Email Takeover

原文の説明

取得元が公開している説明をそのまま載せています (多くは英語)。

FreeScout is a free self-hosted help desk and shared mailbox. Prior to version 1.8.214, a low-privileged agent can edit a visible customer and add an email address already owned by a hidden customer in another mailbox. The server discloses the hidden customer’s name and profile URL in the success flash, reassigns the hidden email to the visible customer, and rebinds hidden-mailbox conversations for that email to the visible customer. Version 1.8.214 fixes the issue.
