CWE: CWE-94 \u2014 Improper Control of Generation of Code ('Code Injection')
The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment.

Code:
				foreach ($setting as $varname => $value) {
					// set all group/varname:values which are not in the import file
					if (!isset($_data[$setting_group.'.'.$varname])) {
						$_data[$setting_group.'.'.$varname] = $value;
					}
				}
