Hey Team,

There is reflected xss on https://█████/kinetic/ when certain action results in 404 error.


I am using some random strings paths after kinetic in https://███████/kinetic/ if that path is not exist then it says 404 not found. Strings is not sanitized after kinetic/ due to which any one can able to use Java Script code after kinetic/ and it executed successfully leads to reflected xss.
