Max-level security alert for vibe coders and builders
Last week's news but still ongoing. 39% of publicly exposed web apps may be affected, with vibe-coded apps at even higher risk because many rely on default framework setups. A maximum-severity security flaw has been disclosed in React Server Components and Next.js that can allow unauthenticated attackers to gain full control of a vulnerable server via a single crafted request. In practical terms, this means potential access to your environment variables, secret keys, databases and backend logic. If you have any public apps: (1) check whether they use Next.js or any framework with server-side components, (2) verify whether your version falls within the affected releases, and (3) upgrade immediately to a patched version and redeploy. Non-vibe-coded apps can be affected as well. More info: I can't provide links because they're not allowed in this group, you can google up Security Advisory: CVE-2025-66478.
