Error: cache() was called outside of a request during render (React Server Components)
React's server-side `cache()` memoizes a function's result for the lifetime of a single request — calling it (or reading its cached value) outside that request boundary, such as at module scope or after the request has already finished, throws. Only call the cached function from within components/functions that execute during that request's render.
Security advisory: React Server Components RCE (CVE-2025-55182) — am I affected?
CVE-2025-55182 is a critical remote-code-execution vulnerability affecting the react-server-dom-* packages in React 19.0.0 through 19.2.2, exploitable in apps that use React Server Components (default create-next-app setups included). Pure client-side React apps that don't use RSC aren't affected by this specific CVE. Update to the patched releases (19.0.4, 19.1.5, or 19.2.4 and later) immediately if you use RSC.
