CVE-2026-48759

baptisteArno typebot.io

TypeBot is a chatbot builder tool. Versions 3.15.2 and below have an Insecure Direct Object Reference vulnerability through cross-workspace Theme Template modification and deletion.

This allows any authenticated user to modify or delete theme templates belonging to any other workspace and may expose Template IDs via shared typebots...
