### Description

`Twig\Profiler\Dumper\HtmlDumper` writes `Profile::getTemplate()` and `Profile::getName()` straight into its HTML output without escaping:

```php protected function formatTemplate(Profile $profile, $prefix): string { return \sprintf('%s└ <span style="background-color: %s">%s</span>', $prefix, self::$colors['template'], $profile->getTemplate()); } ```

The template name comes from the loader (the array key for `ArrayLoader`, a row id for a database-backed loader, etc.). When that name is attacker-controlled, the profiler dump emits arbitrary HTML, and any browser that renders it executes the injected markup. This is an output-encoding bug in profiler/debug tooling, not a sandbox escape.

### Resolution

`HtmlDumper` now runs both `Profile::getTemplate()` and `Profile::getName()` through `htmlspecialchars()` before inserting them into the HTML output.

### Credits

Twig would like to thank El Kharoubi Iosif for reporting the issue and Nicolas Grekas for fixing it.
