Bug: Security fix incomplete: vulnerable React version remains
The PR claims to fix the React Server Components RCE vulnerability (CVE-2025-55182) but only upgrades Next.js from 15.2.4 to 15.2.6. The PR description explicitly states the vulnerability affects React versions 19.0.0, 19.1.0, 19.1.1, and 19.2.0, with fixes in React 19.0.1, 19.1.2, etc. However, the react and react-dom dependencies remain at ^19, which resolves to the vulnerable 19.1.1 version in pnpm-lock.yaml. The React packages need to be upgraded to patched versions to fully remediate the RCE vulnerability.
