NVD Description

Note: Versions mentioned in the description apply only to the upstream webpy package and not the webpy package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

webpy web.py 0.76 is vulnerable to Insufficient Session Expiration. The application's session management relies on periodic cleanup to expire sessions instead of checking the last-access time when a session is loaded. As a result, an expired session whose record has not yet been cleaned up can still be replayed and used, allowing an attacker holding a previously valid session cookie to continue accessing protected resources after the configured idle timeout.
