SCA: security update for @typebot.io/js (GHSA-hqmv-v56g-4m47)

medium Tenable Cloud Security Plugin ID 442347

Description

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

 - TypeBot is a chatbot builder tool. In versions prior to 3.16.0, the Typebot viewer (packages/embeds/js)
 renders anchor tags from rich text bubble content without filtering the javascript: URI scheme. A bot
 author can set a link URL to javascript:PAYLOAD, which executes in the visitor's browser context when
 clicked. Since the viewer is typically embedded in a third-party site, the attacker's JavaScript runs in
 the host page's origin and can exfiltrate cookies and session tokens. This can result in any authenticated
 Typebot user (including those on the free tier) being able to create a bot with this payload. Shared bots
 are publicly accessible — no victim authentication is required. This issue has been resolved in version
 3.16.0. (CVE-2026-39964)

Solution

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