CVE-2026-104250: unstructured: Stored XSS via unescaped HTML generation
When unstructured parses an untrusted document and outputs the result as HTML, malicious markup contained in the document (e.g. <img src=x onerror=...>) is left in the output HTML without escaping. When that output is displayed in a browser, the script embedded in the document executes in the viewer’s browser.
