A critical security flaw in React Server Components is sending developers into overdrive as they race to patch a vulnerability that affects nearly 40% of cloud environments. The bug, discovered by Lachlan Davidson and assigned CVE-2025-55182, allows attackers to execute remote code without authentication.
Meta worked with hosting providers to create patches before Wednesday's public disclosure, but security experts warn exploitation is "inevitable" and "truly imminent." The vulnerability affects major frameworks including Next.js, React Router, and RedwoodJS.
While no attacks have been reported yet, researchers expect exploit code to surface within hours, making this a race against time for organizations worldwide.
