Headline
GHSA-m6m8-6gq8-c9fj: Remote Code Execution Vulnerability in Validation Placeholders in CodeIgniter4
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}]'],
]);
