TypeBot is a chatbot builder tool

Overview

TypeBot is a chatbot builder tool. Prior to version 3.17.0, an authenticated user who has read access to any typebot can resume a waiting webhook session that belongs to a different typebot by mixing an authorized typebotId and blockId and a foreign live resultId. The webhook resume handler authorizes the parent typebot first, but then resolves the descendant result only by resultId. As a result, an attacker can inject arbitrary webhook JSON into another typebot's suspended session and advance its execution without any access to the victim typebot. Version 3.17.0 patches the issue.
