Remote Code Execution Vulnerability in Validation Placeholders in CodeIgniter4
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.: ```php $validation->setRules([ 'email' => ['required', 'valid_email, 'is_unique[users.email,id,{id}]'], ]); ``` ### References - https://codeigniter4.github.io/userguide/libraries/validation.html#validation-placeholders - https://codeigniter4.github.io/userguide/incoming/controllers.html#validating-data - https://codeigniter4.github.io/userguide/models/model.html#in-model-validation ### For more information If you have any questions or comments about this advisory: * Open an issue in [codeigniter4/CodeIgniter4](https://github.com/codeigniter4/CodeIgniter4/issues) * Email us at [SECURITY.md](https://github.com/codeigniter4/CodeIgniter4/blob/develop/SECURITY.md)
