Description
CodeIgniter is a PHP full-stack web framework. Prior to 4.7.4, calling UploadedFile::move() without a second argument uses the client-provided filename without sanitization, allowing a remote attacker to use path traversal sequences to write uploaded content outside the intended directory when the application exposes an upload path. This issue is fixed in version 4.7.4.
