  "summary" : "Cross-site Scripting when rendering error messages in laminas-form",
  "details" : "### Impact\n\nWhen rendering validation error messages via the `formElementErrors()` view helper shipped with laminas-form, many messages will contain the submitted value. However, in vulnerable versions of laminas-form, the value was not being escaped for HTML contexts, which can potentially lead to a Reflected Cross-Site Scripting (XSS) attack.\n\n### Patches\n\nThe following versions were issued to mitigate the vulnerability:\n\n- 2.17.1\n- 3.0.2\n- 3.1.1\n\n### Workarounds\n\nAt the top of a view script where you call the `formElementErrors()` view helper, place the following code:\n\n```php\nuse Laminas\\Form\\ElementInterface;\nuse Laminas\\View\\PhpRenderer;\n\n$escapeMessages = function (ElementInterface $formOrElement, PhpRenderer $renderer): void {\n    $messages = $element->getMessages();\n    if (! $messages) {\n        return;\n    }\n\n    $escaped  = [];\n    array_walk_recursive(\n        $messages,\n        static function (string $item) use (&$escaped, $renderer): void {\n            $escaped[] = $renderer->escapeHtml($item);\n        }\n    };\n\n    $element->setMessages($escaped);\n};\n```\n\nBefore calling `formElementErrors()` with a form, fieldset, or element, call the above closure as follows\n\n```php\n// Usage with a form\n// $this is the view renderer\n$escapeMessages($form, $this);\n\n// Usage with a fieldset\n// $this is the view renderer\n$escapeMessages($fieldset, $this);\n\n// Usage with a form element\n// $this is the view renderer\n$escapeMessages($element, $this);\n```\n\n### For more information\n\nIf you have any questions or comments about this advisory:\n\n* [Open an issue](https://github.com/laminas/laminas-form/issues/new)\n* Email us at [security@getlaminas.org](mailto:security@getlaminas.org)",
