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.\nhttps://www.cve.org/CVERecord?id=CVE-2026-108260https://github.com/tinacms/tinacms/security/advisories/GHSA-c42q-qvc3-j6vghttps://github.com/tinacms/tinacms/pull/7523https://github.com/tinacms/tinacms/commit/5295e077f0d279c35686a0e481a15e33a4877e3bhttps://github.com/tinacms/tinacms/releases/tag/@tinacms/web-components@0.2.1#tinacms #@tinacms #web-components#CVE_2026_108260#bot", "creation_timestamp": "2026-10-09T20:52:42.574461Z"} 2026-10-09T20:52:42.574461+00:00
