CVE-2026-47704: Baptistearno Typebot.io

High severity, CVSS 7.1. EPSS: 0.6% chance of exploitation in the next 30 days.

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.
