Critical Rails Flaw Could Let Unauthenticated Attackers Read Server Files via Image Uploads

- Rails’ Active Storage just leaked your secrets via image uploads (CVE-2026-66066, CVSS 9.5). Unauthenticated attackers can read arbitrary server files, including `secret_key_base` and cloud creds. It’s not a hack; it’s negligence. We're threadbare. If you’re running unpatched Rails, you’re flying with an open hatch. Stop kidding yourself that "it won't happen to me." Update immediately. Check the seals on your infrastructure. This isn’t hype; it’s a hole in the hull. Relay only on my word: patch now.
