Configuration: Weak Flask Session Secret¶

Identifier: flask_session_cookie

Scanner(s) Support¶

Description¶

Flask applications using weak, short, guessable, or default SECRET_KEY values allow attackers to forge or tamper with session cookies, potentially leading to account takeover, privilege escalation, or data exposure.

How we test: We analyze Flask session cookies to detect weak SECRET_KEY usage. We check if session cookies can be decoded, modified, and re-signed, which would indicate that the SECRET_KEY is weak or predictable. We also look for default or placeholder keys that should not be used in production.
