CVE-2026-48759: CWE-639: Authorization Bypass Through User-Controlled Key in 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. The handleSaveThemeTemplate and handleDeleteThemeTemplate handlers validate that the authenticated user is a non-guest member of the provided workspaceId, but then operate on themeTemplateId via Prisma queries that do NOT include workspaceId in the WHERE clause. This allows any authenticated user to modify or delete theme templates belonging to any other workspace and may expose Template IDs via shared typebots or network traffic. This issue has been fixed in version 3.16.0.
AI Analysis
Technical Summary
TypeBot.io versions 3.15.2 and earlier contain an Insecure Direct Object Reference vulnerability where the handleSaveThemeTemplate and handleDeleteThemeTemplate functions validate user membership on workspaceId but perform Prisma queries on themeTemplateId without including workspaceId in the WHERE clause. This flaw enables any authenticated user to modify or delete theme templates belonging to other workspaces, potentially exposing template IDs via shared typebots or network traffic. The vulnerability is addressed in version 3.16.0.
Potential Impact
An attacker with authenticated access can bypass authorization controls to modify or delete theme templates in any workspace, leading to integrity loss of theme templates and potential exposure of template identifiers. The vulnerability does not impact confidentiality but can cause high impact on integrity and low impact on availability.
Mitigation Recommendations
Upgrade to TypeBot version 3.16.0 or later, where this authorization bypass vulnerability has been fixed. Patch status is confirmed by the vendor's versioning information. No additional mitigations are indicated.
