CVE-2026-47704
CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N
Summary
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.
