Angular package, has been categorized as having a moderate severity rather than being labeled as important due to several factors. While the regular expression used for splitting the value of the ng-srcset directive is susceptible to super-linear runtime caused by backtracking, the practical exploitation of this vulnerability requires a large, carefully-crafted input. This input, which triggers catastrophic backtracking and potential denial of service, would not be easily achievable in typical use cases.
