Python CVEs published and patched, by year
14 published in the last 12 months · data refreshed 2026-08-09
At the last-12-month rate of 14 Python CVEs, running 3.14 for a year past 31 Oct 2030 means roughly that many vulnerabilities fixed upstream but never backported to your branch. Past branches bear this out: Python 3.9 has missed 13 since it went end of life.
