TypeBot is a chatbot builder tool. In versions 3.15.2, the getLinkedTypebots API endpoint returns full bot definitions to any authenticated user who references a target bot ID in a Typebot Link block, regardless of workspace ownership, leading to IDOR. The authorization check uses Array.filter() with an async callback — since filter() is synchronous, the callback always returns a truthy Promise, so the access control predicate is never actually evaluated. Any authenticated Typebot user can read the full definition of any other workspace's private bots, including: all conversation blocks and logic flow, variable values embedded in the bot (credentials, API keys, PII), webhook URLs and integration configurations. This issue has been fixed in version 3.16.0.
