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 Session Fixation. The component Session._load() reads session_id directly from the request cookie and loads that session from the store, and _save() writes back under the same session_id; no rotation after authentication, so a fixed session_id keeps the authenticated state.
