Contao before 4.4.52, 4.9.x before 4.9.6, and 4.10.x before 4.10.1 have Improper Input Validation. It is possible to inject insert tags in front end forms which will be replaced when the page is rendered.
The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.
