CVE-2025-55182 is a critical pre-auth RCE in React Server Components affecting react-server-dom-webpack/turbopack/parcel at version 19.2.0. CVSS 10.0, EPSS 0.996, CISA KEV-listed. SMRY uses Next.js App Router (RSC enabled) with react@19.2.0 and react-dom@19.2.0, making it directly vulnerable. Fix: bump react and react-dom to 19.2.1 which contains the patch. Build verified: Turbopack compiles, TypeScript passes. Refs: GHSA-fv66-9v8q-g76r, CVE-2025-55182

Summary
Fixes CVE-2025-55182 — a critical pre-authentication remote code execution vulnerability in React Server Components.
Vulnerability Details
Affected Packages
The vulnerability is in React Server Components serialization/deserialization:
These are internal packages bundled within react-dom@19.2.0 and used by Next.js App Router for RSC data serialization.
Impact on SMRY
SMRY uses next@16.0.0 with the App Router (RSC enabled by default) and react@19.2.0 + react-dom@19.2.0 — directly in the vulnerable range. Multiple use client directives confirm active RSC usage. This makes SMRY directly vulnerable to unauthenticated RCE via crafted RSC payloads.
Fix
Bump react and react-dom from 19.2.0 to 19.2.1 in package.json and regenerate pnpm-lock.yaml.
