Bug

File: internal/service/auth/auth.go, New(), line ~70

Severity: MEDIUM — Session hijacking

Description

The session cookie store is configured without the Secure flag:

store.Options = &sessions.Options{
    Path:     "/",
    MaxAge:   sessionMaxAgeSeconds,
    HttpOnly: true,
    SameSite: http.SameSiteLaxMode,
}

Without Secure: true, the session cookie will be sent over plaintext HTTP connections, making it vulnerable to interception by network attackers (e.g., on shared Wi-Fi).

Suggested Fix

Add Secure: true to the cookie options, or make it configurable based on whether the app is behind TLS:

store.Options = &sessions.Options{
    Path:     "/",
    MaxAge:   sessionMaxAgeSeconds,
    HttpOnly: true,
    Secure:   true,
    SameSite: http.SameSiteLaxMode,
}
