return http.Cookie{Name: "session", Value: v, Secure: false}Passes - the safe pattern
return http.Cookie{Name: "session", Value: v, Secure: true, HttpOnly: true}Why it matters & how to fix it
A cookie is created without the Secure and/or HttpOnly flags (CWE-614/CWE-1004). Without Secure the cookie is sent over plaintext HTTP; without HttpOnly it is readable by JavaScript and stealable via XSS. Set Secure: true, HttpOnly: true, and an appropriate SameSite value on all session/auth cookies.
