Could someone suggest on below risk raised by checkMarx tool for ASp.NET Core WebAPI, as application don't send or store any cookies.

" Startup.cs application configuration file, at line 21, does not define sensitive application cookies with the "secure" flag, which could cause the client to send those cookies in plaintext over an insecure network communication (HTTP). This may lead to a Session Hijacking attack."

line 21 mentions --- public class Startup

What I have tried:

I have tried ways to add app.UseHsts();app.UseHttpsRedirection(); to request pipeline, not resolved the issue.

What do you think we could possibly suggest, given we can't see any of the code in question? If the tool says you have a security problem with your code, then you probably have a security problem with your code.
