## Athena Session Cookie Security Flaw: Secure Flag Missing, Session Tokens Exposed Over HTTP
A critical security misconfiguration in the Athena platform exposes user session tokens to potential interception. The platform's primary authentication cookie, 'athena-session', and its OAuth2 state cookie are being set without the mandatory 'Secure' flag. This omission means that if any part of the application flow occurs over an unencrypted HTTP connection—due to a server misconfiguration, mixed-content issues, or even a development environment oversight—the sensitive session token is transmitted in plaintext, completely unprotected.

The vulnerability, classified as a Medium severity issue under the OWASP A02:2021 Cryptographic Failures category, is rooted in the application's source code. In the authentication callback route, the cookie is explicitly set with `httpOnly: true` and `sameSite: 'lax'` protections, but the `secure: true` property is conspicuously absent. An identical flaw exists in the login route for the OAuth state cookie. This directly violates a foundational OWASP session management requirement, which mandates the Secure flag for all authentication cookies to ensure they are only sent over HTTPS.

The immediate impact is a clear elevation of risk for session hijacking. Any scenario where the application is accessed or redirected via HTTP—whether in production due to an error or commonly in development and testing—transforms the session identifier into readable network traffic. This flaw undermines the other security measures in place, creating a single point of failure that could compromise user accounts and system integrity without requiring a complex attack.
