CVE-2026-47704
Full vulnerability record from the local CVENow database.
Description
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.

"value": "TypeBot es una herramienta de creación de chatbots. Antes de la versión 3.17.0, un usuario autenticado que tiene acceso de lectura a cualquier typebot puede reanudar una sesión de webhook en espera que pertenece a un typebot diferente mezclando un ’typebotId’ y ’blockId’ autorizados y un ’resultId’ en vivo ajeno. El gestor de reanudación del webhook autoriza primero el typebot padre, pero luego resuelve el ’result’ descendiente solo por ’resultId’. Como resultado, un atacante puede inyectar JSON de webhook arbitrario en la sesión suspendida de otro typebot y avanzar su ejecución sin ningún acceso al typebot víctima. La versión 3.17.0 corrige el problema."
