Twig is a template language for PHP. When using the ?? operator, output escaping was missing for the expression on the left side of the operator. This vulnerability is fixed in 3.19.0.
The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.
