SCA: security update for @tinacms/web-components (GHSA-c42q-qvc3-j6vg)

high Tenable Cloud Security Plugin ID 474098

Description

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

 - Tina is a headless content management system. Prior to 0.2.1, the tina-markdown element in
 packages/@tinacms/web-components/src/tina-markdown.js assigns a rich-text node.url value directly to an
 anchor href without validating the URL scheme. A content author can store a link using a script-capable
 scheme, and a visitor who clicks the rendered link executes attacker-controlled script in the site's
 origin. The script can access same-origin application data and, when the visitor is an editor or
 administrator, may expose credentials stored by the TinaCMS admin on that origin. This issue is fixed in
 version 0.2.1. (CVE-2026-108260)

Solution

Update the @tinacms/web-components library and its related packages to version 0.2.1 or later.
