Bug: React remains vulnerable despite CVE fix claim
The PR description claims to fix CVE-2025-55182, a React vulnerability affecting React Server Components, but only next is upgraded while react and react-dom remain at version 19.1.0. According to the Snyk vulnerability database, React 19.1.0 has known vulnerabilities. If the RCE vulnerability exists in React itself (as suggested by the mentioned React Advisory), this fix may be incomplete. The React packages likely need to be upgraded alongside Next.js to fully remediate the vulnerability.
