session-fixation-anti-pattern

Prevent session fixation by regenerating session IDs immediately after user authentication. This Skill detects insecure session management code where IDs are reused, providing secure alternatives to mitigate hijacking risks.

Session fixation is a vulnerability where an attacker predicts or steals a session ID before login to hijack the authenticated session. This Skill analyzes authentication flows to detect and prevent this CWE-384 anti-pattern.

Check your Python Flask code by reviewing authentication flows to ensure old session IDs are invalidated and new ones are created upon login. This Skill detects insecure session reuse and provides secure code examples.

Session IDs must be regenerated after authentication to prevent session fixation attacks. This analysis identifies instances where session IDs are not invalidated, offering secure session state management practices to prevent hijacking.

Yes, this Skill analyzes general web application code for insecure session management practices across platforms. It detects session reuse and provides secure alternatives for authentication flows to mitigate hijacking risks.

This detection focuses on analyzing code for insecure session management practices where IDs are not regenerated post-authentication. It addresses authentication flows and session state changes but requires manual implementation of the secure alternatives provided.
