Ruby on Rails CVEs published and patched, by year
8 published in the last 12 months · data refreshed 2026-08-09
At the last-12-month rate of 8 Ruby on Rails CVEs, running 8.1 for a year past 10 Oct 2027 means roughly that many vulnerabilities fixed upstream but never backported to your branch. Past branches bear this out: Ruby on Rails 7.1 has missed 8 since it went end of life.
