## The brief

CERT-FR's September 30 CPython notice concerns CVE-2026-12345, which the agency says can compromise data integrity. It identifies CPython installations lacking the latest security patch as affected rather than listing individual release branches. The advisory refers maintainers to the Python Software Foundation's PSF-2026-42 bulletin, dated September 29, for the relevant correction details.
