Technical details

This is a Cross-Site Scripting (CWE-79) vulnerability in the Select schema renderer. The vulnerable code in packages/schemas/src/select/index.ts (lines 159-164) builds HTML for <option> elements by directly interpolating unsanitized option values from the template JSON into an HTML string, then assigns it to innerHTML. An attacker can break out of the value attribute using a payload like `"></option><img src=x onerror="alert(document.domain)">` in the schema.options array. The attack vector is network-based with no privilege requirement but requires user interaction (viewing/rendering the template). Attack preconditions include the ability to supply or upload a malicious template, which can occur via file upload, shared templates in multi-tenant apps, or databases without sanitization. The fix is to use DOM APIs (createElement, appendChild) instead of innerHTML, or to HTML-encode option values before interpolation. Versions <= 5.5.8 are affected; version 5.5.9+ contains the patch.
