CVE-2026-79312

Name	CVE-2026-79312
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.
Source	CVE (at NVD; CERT, ENISA, LWN, oss-sec, fulldisc, Debian ELTS, Red Hat, Ubuntu, Gentoo, SUSE bugzilla/CVE, GitHub advisories/code/issues, web search, more)
