Valinor is a PHP library that helps to map any input into a strongly-typed value object structure. Prior to version 0.12.0, Valinor can use `Throwable#getMessage()` when it should not have permission to do so. This is a problem with cases such as an SQL exception showing an SQL snippet, a database connection exception showing database IP address/username/password, or a timeout detail / out of memory detail. Attackers could use this information for potential data exfiltration, denial of service attacks, enumeration attacks, etc. Version 0.12.0 contains a patch for this vulnerability.

GHSA-5pgm-3j3g-2rc7 — Valinor error messages leading to potential data exfiltration before v0.12.0

Affected: Packagist: cuyz/valinor

```php <?php

namespace My\App;

use CuyZ\Valinor\Mapper\MappingError; use CuyZ\Valinor\Mapper\Tree\Node; use CuyZ\Valinor\Mapper\Tree\NodeTraverser; use CuyZ\Valinor\MapperBuilder;

require_once __DIR__ . '/Valinor/vendor/autoload.php';

final class Money { private function __construct(public readonly string $amount) { }

public static function fromString(string $money): self { if (1 !== \preg_match('/^\d+ [A-Z]{3}$/', $money)) { throw new \InvalidArgumentException(\sprintf('Given "%s" is not a recognized monetary amount', $money)); } return new self($money); } }

class Foo { public function __construct( private readonly Money $a, private readonly Money $b, private readonly Money $c, ) {} }

$mapper = (new MapperBuilder()) ->registerConstructor([Money::class, 'fromString']) ->mapper();

try { var_dump($mapper->map(Foo::class, [ 'a' => 'HAHA', 'b' => '100 EUR', 'c' => 'USD 100' ])); } catch (MappingError $e) { $messages = (new NodeTraverser(function (Node $node) { foreach ($node->messages() as $message) { var_dump([ '$message', $message->path(), $message->body() ]); } return ''; }))->traverse($e->node());

iterator_to_array($messages); } ```

Now, this is quite innocent: it produces following output:
