In Laravel website, I did vulnerability test and I did not understand the meaning of this issue. Can anyone help on this.

The query time is controllable using parameter value [' | case randomblob(10000000) when not null then "" else "" end --], which caused the request to take [1,292] milliseconds, parameter value [' | case randomblob(100000000) when not null then "" else "" end --], which caused the request to take [1,330] milliseconds, when the original unmodified query with value [[email protected]] took [299] milliseconds.
