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.","state":0,"publishedAt":"2026-10-09T21:17:04.18+00:00","modifiedAt":"2026-10-16T20:04:29.76+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:L/A:N","score":7.6,"severity":"HIGH"}],"references":["https://github.com/tinacms/tinacms/commit/5295e077f0d279c35686a0e481a15e33a4877e3b","https://github.com/tinacms/tinacms/pull/7523","https://github.com/tinacms/tinacms/releases/tag/@tinacms/web-components@0.2.1","https://github.com/tinacms/tinacms/security/advisories/GHSA-c42q-qvc3-j6vg"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-108260","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-79","CWE-83"],"productCriteria":[],"sourceDates":{"published":"2026-10-09T21:17:04.180","lastModified":"2026-10-16T20:04:29.760"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
