Bug: The package-lock.json pins react and react-dom to version 19.1.0, which remains vulnerable to CVE-2025-55182. The security fix is incomplete.
Severity: CRITICAL | Confidence: High
🔍 Detailed Analysis
This pull request intends to patch React Server Components vulnerabilities, including CVE-2025-55182. However, the package-lock.json explicitly pins react and react-dom to version 19.1.0. The minimum safe version required to fully patch the vulnerability is 19.1.4. As a result, the application remains vulnerable to Remote Code Execution (RCE) attacks, defeating the purpose of this security fix. The locked versions do not contain the complete protection against the disclosed vulnerabilities.
💡 Suggested Fix
Update the dependencies and regenerate package-lock.json to ensure react and react-dom are pinned to a safe version, such as 19.1.4 or higher, which contains the complete patch for CVE-2025-55182 and related vulnerabilities.
