CVE-2026-48759
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedTypeBot 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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceTypeBot versions 3.15.2 and below contain an Insecure Direct Object Reference (IDOR) vulnerability in the handleSaveThemeTemplate and handleDeleteThemeTemplate handlers. While the handlers correctly validate that the authenticated user is a non-guest member of a workspace, the Prisma queries operating on themeTemplateId do NOT include workspaceId in the WHERE clause, allowing any authenticated user to modify or delete theme templates from any other workspace.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify installed TypeBot versionLocate the TypeBot installation and determine its version number from package.json, docker image tag, or application metadata. Compare against affected range: versions 3.15.2 and below.Affected if Running version 3.15.2 or lower
-
Confirm theme template feature is activeCheck if the handleSaveThemeTemplate and handleDeleteThemeTemplate API endpoints are exposed and functional in the application. This may require examining the API routes or checking if theme templates exist in the database.Affected if Theme template handlers are accessible and theme templates exist in the system
-
Verify user authentication is enabledConfirm that the application requires authentication for workspace access. The vulnerability requires an authenticated non-guest user session to exploit.Affected if Authentication is enabled and users can access the workspace
-
Audit Prisma queries for missing workspaceId filterReview the source code for handleSaveThemeTemplate and handleDeleteThemeTemplate handlers. Examine the Prisma queries operating on themeTemplateId and verify whether workspaceId is included in the WHERE clause.Affected if Queries on themeTemplateId do NOT include workspaceId in the WHERE clause
User is affected if running TypeBot version 3.15.2 or below with authenticated user access to theme template handlers, and the Prisma queries lack workspaceId validation in the WHERE clause.
