CVE-2026-79312
webpy web.py 0.76 is vulnerable to Session Fixation.
MEDIUM 6.8EPSS 0.29%
Does this matter?
Lower severity and a low EPSS score (0.29%). Track it; it rarely justifies an emergency change on its own.
Description
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.
