Description

Impact

This vulnerability allows attackers to execute arbitrary code when you use Validation Placeholders.

The vulnerability exists in the Validation library, and validation methods in the controller and in-model validation are also vulnerable because they use the Validation library internally.

Patches

Upgrade to v4.3.5 or later.

Workarounds

Setting validation rules with an array.

E.g.:

$validation->setRules([
    'email' => ['required', 'valid_email, 'is_unique[users.email,id,{id}]'],
]);
