|---|
| 説明 | PHP-FTS (ols/php-fts) before an unreleased fix does not HTML-escape document field values in `SearchEngine::buildHighlights()` before wrapping matched words in HTML highlight tags. The `search($query, highlight: true)` path splits field values into words and concatenates matched words as `$openTag . $word . $closeTag` (default `<mark>...</mark>`) with no `htmlspecialchars()`. When an application indexes attacker-influenced content and renders the returned highlights as HTML, an attacker can inject arbitrary markup (e.g. an `<img src=x onerror=alert(document.cookie)>` payload) that executes in the browser of users viewing search results, leading to stored cross-site scripting (session/cookie theft, account takeover).
