React2Shell Exploiting React Server Components

The sources come from a KeysGuard cyber intelligence briefing focused on the critical, fast-moving React2Shell vulnerability (CVE-2025-55182). The alerts stress the serious risk this flaw poses to internet-facing apps built on React or Next.js, calling for urgent action due to how quickly it’s being exploited. They outline specific defensive steps and technical details, including key indicators of compromise (IoCs) to aid detection, and stress the importance of emergency patching for affected server components. The briefing also sets broader December 2025 patch priorities, like the Android security update, and points to the growing trend of a much shorter gap between vulnerability disclosure and active attacks.
