SCA: security update for @typebot.io/js (GHSA-6m7c-xfhp-p9fh)

high Tenable Self-Hosted Container Security Plugin ID 442349

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Typebot is a chatbot builder tool. In versions 3.15.2 and prior, the RatingButton component in the embed
 package renders the user-controlled customIcon.svg field directly via Solid's innerHTML directive without
 any sanitization, even though DOMPurify is already a dependency and is used elsewhere in the codebase
 (e.g., StreamingBubble.tsx). Because rating blocks are not flagged as isUnsafe by the import sanitizer and
 the builder preview renders bots inline on the builder's own origin (builder.typebot.io) under a CSP
 permitting 'unsafe-inline', a malicious imported or collaborator-crafted typebot can execute arbitrary
 HTML/JS in the builder's authenticated context, bypassing the Web Worker sandbox that protects Script
 blocks during preview. This allows session hijacking and privilege escalation within the builder
 application. This issue has been fixed in version 3.16.0. (CVE-2026-28445)

Solution

Update the @typebot.io/js library and its related packages to version 0.10.1 or later.
