FreeScout's cross-user undo reply allows mailbox peers to recall another agent's outbound reply

概要

FreeScout's cross-user undo reply allows mailbox peers to recall another agent's outbound reply

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, the undo-send route GET /conversation/undo-reply/{thread_id} checks only whether the current user can view the parent conversation. It does not verify that the current user created the reply being undone. In a shared mailbox, one agent can therefore recall another agent's just-sent reply during the 15-second undo window. Version 1.8.214 fixes the vulnerability.
